Question

Construct a triangle PQR, given that PQ = 5 cm and $∠ Q P R = 60^{\circ}$ and $∠ Q R P = 45^{\circ}$ .

Open in App

Solution

Draw a line segment PQ of length 5 cm.

At P, draw a ray PX by making an angle of $60^{\circ}$ with PQ (according to the given condition, R lies on ray PX).

At Q, draw a ray QY by making an angle of $45^{\circ}$ with PQ (according to the given condition, R also lies on ray QY).

The intersection point of ray PX and QY is the point where R lies.
