Question

Draw $△PQR$ with $PQ=4$ cm, $QR=3.5$ cm and $PR=4$ cm. What type of triangle is this?

Answer 1

Draw a line $QR=3.5$ cm.

From points $Q$ and $R$, draw arcs with radii $=PQ=PR=4$ cm.

Join the point of intersection of both arcs with points $Q$ and $R$ to get the required triangle.

This is an isosceles triangle.
