Question

We are given two unequal angles of a
triangle and a side between them. To
construct such triangle, we should first
draw:

Answer 1

Answer:

Step 1 :

Draw the line segment QR = 6.5 cm.

(Here we take the longest side)

Step 2 :

Using protractor, at Q, draw a line QX making an angle of 60° with QR.

Step 3 :

With Q as centre, draw an arc of radius 4 cm to cut the line (QX) at P.

Step 4 :

Join PR.

Now, PQR is the required triangle.

This construction clearly shows how to construct a triangle with the mathematical instruments compass, ruler and protractor when two sides and an included angle are given
