Question

If angle c =70 degree, find angle a, angle d, angle b .

Answer 1

<a = 70 ( V.O.A)

<d = 180 - 70 = 110 (Linear pair )

<b = 110 (V.O.A)

Answer 2

Given:
Angle c= 70°

angle c = angle a.--------(opposite angle)
angle a = 70°

angle b =180-70
= 110°----------(angle a and b is in linear pair)


angle b = angle d--------(opposite angle)
angle d = 110°
