Angle

If the incentre of an equilateral triangle lies inside the triangle and its radius is $3 \mathrm{cm}$, then the side of the equilateral triangle is:

What is angle?

In figure, $\angle AOB\cong \angle BOC\cong \angle COD$. Name the angle which is congruent to $\angle AOC$. Give reasons in support of your answer.

If the base is same for angles and the length of arms is also same, can we conclude that two angles are equal?

Draw the lines to match the angles that are the same size.

Describe the angles compared to a right angle.

Find and draw $4$ angles in your classroom:

The below angle is smaller or larger than $90°$ ?

The below angle is smaller or larger than $90°$ ?

The below angle is smaller or larger than $90°$ ?

The below angle is smaller or larger than $90°$ ?

The below angle is smaller or larger than $90°$ ?

The below angle is smaller or larger than $90°$ ?
