Question

Arrange the given shapes in increasing order according to the measure of their angles inside them.

Answer 1

Each shape given here is made of sides that are of equal length.

For such shapes:
Shape having more number of sides have larger angles inside them.

Number of sides of :
Shape 1 = 5 sides
Shape 2 = 10 sides
Shape 3 = 7 sides

So shape 1 will have the smallest angles and shape 2 will have largest angles inside them.

Thus, the inncreasing order for the shape according to their angle measure is 1 < 3 < 2.
