Answer 1

S O L U T I O N :

[ For question one ]

Given,

• A and B are respectively the mid point of sides PQ and QR.
• Angle PAB = 60°

To Find,

• The value of Angle PQR.

Explanation,

In ΔPQR,

Given, A and B are respectively the mid point of sides PQ and QR.

=> .°. Angle PAB = Angle PQR

(Corresponding angle)

=> 60° = Angle PQR

=> .°. Angle PQR = 60°

Therefore,

• The value of Angle PQR is 60°.

[ For question second ]

A line segment joining the mid - point of any two sides of a triangle, is Parallel to the third side and is equal to Half of it.
