Question

31 colour the prisms yellow. colour the pyramids purple. colour the other three - dimensional figures orange. 32 circle the acute angles. underline the right angles. draw a square around the obtuse angles.

Explanation:

Step1: Identify prisms

Prisms have two congruent and parallel bases. Colour the appropriate 3 - D figures yellow.

Step2: Identify pyramids

Pyramids have a base and triangular faces that meet at a single point. Colour them purple.

Step3: Identify other 3 - D figures

Colour the remaining 3 - D figures (like cylinder, sphere) orange.

Step4: Identify acute angles

Acute angles are less than 90°. Circle them.

Step5: Identify right angles

Right angles are exactly 90°. Underline them.

Step6: Identify obtuse angles

Obtuse angles are greater than 90° and less than 180°. Draw a square around them.

Answer:

You need to perform the above - described actions (colouring and marking) on the given figures in the picture.
