Question

check whether the following statements are true or not.
1. a+b=d+c
2. a+c+e=180°
b+f=c+e

Answer 1

Hey
1 ) True as Angle d and angle a are equal so we can put value of d as a. (Vertically opposite angles)

2) Yes it is also true as we can put angle d at place of angle a and angles d, c,e form a line.

3) False as angle b + c = f + e ( Vertically opposite angles) .
Therefore, b-f = e - c.

Hope it helps :)
