Q 3. Draw ∆PQR with PQ = 4 cm, QR = 3.5 cm and PR = 4 cm. What type of triangle is this?
PQR with PQ = 4 cm, QR = 3.5 cm and PR = 4 cm:
1.Draw a line QR = 3.5 cm
2. With Q as centre and length = 4 cm draw an arc
3. With R as centre and length = 4cm draw another arc to cut the previous arc at P
4. Join QP and QR. Then PQR is the required triangle
As we can see two sides of the triangle are same so The triangle is an isosceles triangle.
