Question

Mohini made each of these shapes with 6 match sticks. Look at the angles inside the given shapes. Are the angles of these shapes with same number of sides same? Explain.

Answer 1

All the 3 shapes here are made up of 6 match sticks but look different.
All the angles in the first shape are obtuse angles.
The secong shape has an angle greater than 180${}^{\circ }$.
All the angles inside the third shape are acute angles.

So, it is not necessary that if different shapes have same number of sides then all of them have same measure of angle.
