Answer 1

Step-by-step explanation:

1.) Sum of all angles of a pentagon = (n-2)×180° (n is number of sides)

= (5-2)×180° = 3×180° = 540°

Therefore one angle = 540°/5 = 108°

2.) One vertex can be joined to (5-1) vertices.

Since, 2 of them are sides of pentagon.

Therefore, from 1 point total 4-2=2 diagonals can be drawn
