Question

1 point
Q7. Which point in the
figure lie in the exterior of
triangle PQR? *
-D​

Answer 1

Answer:

Given:

Triangle ABC is an isosceles triangle.

Or AB =AC

Or ∠ABC=∠ACB        (Since its an isosceles triangle)

Now, we have:

x + y =180°     ...(1) (Linear pair)x + z =180°      ...(2) (Linear pair)

Subtracting (1) and (2), we get:

y−z=0⇒y=z

Thus, the exterior angles so formed are equal to each other.

Hence, proved.

Answer 2

Answer:

extend a line from R

till point S then

angle PRS will be exterior angle
