Question

In the given figure , AB||CD. Prove that p+q-r=180.

Answer 1

Answer:

Heyya Mate!! So here is your answer...

Step-by-step explanation:

Draw a line  parallel to AB and CD passing through F. (Chk the image attached below)

From the figure,

p° + x° =180° .......(1)

(Sum of interior angles same side of the transversal are supplementary)

r° = y° ........(2)

(alternate angles)

Therefore,

x° + y° = q°

=> x° = q° - y°

=> x° = q° - r° .......(3)    [From (2)]

Now, put (3) in equation (1), we get

p° + q° - r° = 180°
