Question

In fig. l is parallel to m and n is parallel to p and angle 1 is of 60 degree.Find that angle 2 is the double of angle 1​

Answer 1

Answer:

Angle X = 2Angle 1

Step-by-step explanation:

This can be easily proved

Since, p||n and l is a Transversal

Hence, Angle 1 = Angle x = 60°

(Corresponding Angles are Equal)

Again, Angle 2 + Angle x = 180° (Cointerior Angles)

but Angle 1 =60° (Given)

Hence, Angle x = 180°-60°=120°

Therefore, Angle x = 2Angle 1
