Question

Students should take examples of their own and practise the construction of triangles.

Geometric Constructions

Solution

In ∆PQR, l(PR) = 8 cm, m ∠PQR = 90° , l(QR) = 6 cm. 

Steps of construction:

  1. Draw a line QR = 6 cm.
  2. With Q as centre, draw ∠XQR = 90º.
  3. With R as centre and 8 cm as radius, cut an arc on XQ and name it as point P.
  4. Join PR.

∆PQR is thus formed.
