Question

# Identify and name two acute angles.

Hint:

- Angles whose measure is more than 0 but less than 90 are called ‘acute angles’.
- Angles whose measure is more than 90 but less than 180 are called ‘obtuse angles’.
- Angles whose measure 90 are called ‘right angles’.

## The correct answer is: ∠COD and ∠BOA

- Step by step explanation:

- Step 1:

As we know, angles whose measure is 90^{o} are right angles.

Hence, angle ∠POD and ∠POA are right angles.

From the figure,

It is clear that,

∠COD is less than ∠POD and ∠BOA is less than ∠POA

∴ ∠COD < 90^{o}and ∠BOA < 90^{o}

Hence, ∠COD and ∠BOA are acute angles.

- Final Answer:

Hence, ∠COD and ∠BOA are two acute angles.

- Step by step explanation:

- Step 1:
