Question

Prove that angle a= angle b+ angle c

Answer 1

Step-by-step explanation:

Given: AB || CD and AD is the transversal.

To prove: Angle a = Angle b + Angle c

Proof:

Angle C = Angle BAD (Alt. interior Angles)

Now, Angle b + Angle BAD = Angle a

(Exterior Angle is equal to the sum of the two opposite interior angles)

=> Angle b+ Angle c = Angle a (Proved)
