Question

In the following figure, prove that x+y = z

Answer 1

Answer:

Step-by-step explanation:

We know that,

Angle sum property of triangle= 180°

<BAD+<x+<y = 180°. (1)

And,

Sum of two opposite interior angle = 180°

< BAD+< z=180

<BAD= 180-< z. (2)

On putting equation (2) in equation (1),we get

180-<z+<x +<y=180

<x +<y =<z

Hence,proved.
