The idea in one minute

The sun fixes the direction of every shadow. In the morning the sun is in the East, so shadows point West. In the evening the sun is in the West, so shadows point East. Turn the shadow words into a sentence about which way the person faces, then finish the question.

01

The sun points the shadow

A shadow always falls away from the sun. So the sun does the pointing for you.

TimeSun is in theShadow points
Morning (sunrise)EastWest
Evening (sunset)WestEast

At noon in India, the shadow points roughly North. Most questions avoid noon.

Rule: Write "morning: shadow West" or "evening: shadow East" before you read anything else.

02

Where the shadow falls on the body

A person faces some direction. The shadow can fall in front, behind, on the left or on the right.

  • Shadow in front: he faces the same way as the shadow.
  • Shadow behind: he faces the opposite way.
  • Shadow on the left or right: he faces a direction at right angles to the shadow.

Example: morning, shadow falls in front of him. The shadow points West, so he faces West. If it falls behind him, he faces East.

03

Left and right shadows

Use the body map. It tells you what lies on the left and right for each facing.

He facesLeft isRight is
NorthWestEast
SouthEastWest
EastNorthSouth
WestSouthNorth

Example: morning, shadow falls on his right. The shadow points West. West is on his right when he faces South. So he faces South.

Tip: For a morning shadow, left means facing North and right means facing South. For an evening shadow, left means South and right means North.

04

Two people, back to back

Back to back means the two people face opposite ways. Find one person's facing from the shadow. The other faces the opposite way.

Example: evening, Rohit's shadow falls on his left. The shadow points East. So Rohit faces South. His partner stands back to back with him, so he faces North.

05

Four pictures to learn

Most questions use only these four. Learn them by heart.

The left and right cases follow from the body map above.

06

Shadow and then a movement

Some questions add a walk or a turn. Do it in three steps.

  1. Turn the shadow into a compass direction for that time.
  2. Turn "towards" or "away from the shadow" into a plain direction.
  3. Finish with quarter-turns on the circle North, East, South, West.

Example: evening, a man walks away from his shadow. The shadow points East, so he walks West. He then turns 90 degrees anticlockwise and faces South.

Watch: The shadow is not the direction he faces. Read which of the two the question asks for.

07

Question types you will see

Each type: how to recognise it, the method step by step, and one question to try.

Type 1very common3 practice Q

Morning shadow

How to spot it:

The time is early morning or sunrise. The shadow is in front, behind, left or right of a person.

Method
  1. Write: morning, shadow West.

  2. Front means he faces West. Behind means he faces East.

  3. Left means he faces North. Right means he faces South.

Why it works:

The shadow is a fixed compass arrow. The person turns to put it on the stated side.

Try this

At sunrise, a man's shadow falls exactly behind him. Which way is he facing?

Show solution
  1. Morning: the shadow points West.

  2. The shadow is behind him, so he faces the opposite way.

  3. Opposite of West is East.

Answer

East

Type 2very common3 practice Q

Evening shadow

How to spot it:

The time is evening or sunset. The shadow is in front, behind, left or right of a person.

Method
  1. Write: evening, shadow East.

  2. Front means he faces East. Behind means he faces West.

  3. Left means he faces South. Right means he faces North.

Why it works:

It is the same rule as morning, with the shadow arrow turned around.

Try this

One evening, Ramesh's shadow falls exactly in front of him. Which way is he facing?

Show solution
  1. Evening: the shadow points East.

  2. The shadow is in front, so he faces the same way.

Answer

East

Type 3common2 practice Q

Left or right shadow to facing

How to spot it:

The shadow falls to the left or right of the person, and his facing is asked.

Method
  1. Write the shadow direction for that time.

  2. Look at the body map. Find the facing that puts that direction on the stated side.

  3. Check by holding out your hand.

Why it works:

Only one of the four facings puts the shadow on the stated side.

Try this

In the evening, Neha's shadow falls on her left. Which way is she facing?

Show solution
  1. Evening: the shadow points East.

  2. When she faces South, her left is East.

  3. So she faces South.

Answer

South

Type 4common2 practice Q

Shadow, then a walk or a turn

How to spot it:

The person walks towards or away from the shadow, or turns by 90 or 180 degrees, and the final direction is asked.

Method
  1. Turn the shadow into a compass direction.

  2. Turn 'towards' or 'away' into a direction. Away means the opposite.

  3. Finish the turns with quarter-turns.

Why it works:

After the first step, it is an ordinary final-facing question.

Try this

In the evening, Kiran walks away from his shadow. He then turns 90 degrees anticlockwise. Which way does he face now?

Show solution
  1. Evening: the shadow points East.

  2. Away from it means he walks West.

  3. Anticlockwise from West is South.

Answer

South

Type 5occasional

Two people back to back

How to spot it:

Two people stand back to back, and one shadow position is given. The other person's facing or shadow side is asked.

Method
  1. Find the first person's facing from his shadow.

  2. Back to back means the other person faces the opposite way.

  3. Use the body map to place the shadow for the second person.

Why it works:

Back to back fixes the second person's facing at once.

Try this

In the evening, Rohit and Mohit stand back to back. Rohit's shadow falls on his left. Which way does Mohit face?

Show solution
  1. Evening: the shadow points East. East is on Rohit's left when he faces South.

  2. Mohit faces the opposite way to Rohit.

  3. Opposite of South is North.

Answer

North

Shortcuts that save time

⚡ Change the shadow into a facing first

Before any other step, rewrite the sentence as a facing sentence. Morning and shadow behind him means he faces East. Evening and shadow in front means he faces East.

Example

In the morning, a boy's shadow falls on his left. Which way does he face?

Show solution
  1. Morning shadow points West.

  2. West is on his left when he faces North.

Answer

North

Mistakes to avoid

Where most students lose marks on this subtopic.

Mistake 01

Using the evening shadow direction in a morning question.

Write 'morning: shadow West' or 'evening: shadow East' first.

Mistake 02

Giving the shadow's direction when the question asks the person's facing.

The shadow and the facing are two different arrows. Answer the one asked.

Mistake 03

Forgetting that left and right change when the facing changes.

Use the body map for each facing.

Mistake 04

Treating back to back as facing the same way.

Back to back means the two people face opposite ways.

Mistake 05

Treating 'away from the shadow' as the shadow's direction.

Away from it means the opposite direction.
