Question

Answer the following :-
1. how many angles does a regular pentagon have
2.measure of each angle
3.sum of all angles
4. Sum of external angles of a square

Answer 1

Answer:

Q1 - 5............. angles

Answer 2

1. 5 angles

2.A pentagon has 5 sides, and can be made from three triangles, so you know what ...

... its interior angles add up to 3 × 180° = 540°

3.

And when it is regular (all angles the same), then each angle is 540° / 5 = 108°

4.

Each interior angle in a square is equal to 90 degrees. Notice that an interior angle plus the adjacent exterior angle is equal to 180 degrees. Interior angle + adjacent exterior angle = 180 degrees. In fact, the sum of ( the interior angle plus the exterior angle ) of any polygon always add up to 180 degrees.
