Question

angles inside and outside a triangle

Find the missing angle

Answer 1

Answer:

Angle A = 45

Angle B=45

Angle C =45

Angle D=135

angle E= 135

Answer 2

Answer:

All sides are equal which means it is an equilateral triangle.

So, a = b = c = 60°

Now,

d + b = 180 ( Linear pair of angles)

d + 60 = 180

d = 180 - 60 = 120°

Now,

d = e = 120° (Vertically opposite angles)
