Draw an isosceles triangle with each of equal sides of length 3 cm and the angle between them as 45°.

Solution:

Steps of construction

1. Draw a rough sketch of a triangle with measurements marked on it.

2. Construct a line segment AB of 3 cm

3. Construct an angle 45° on the point B and produce it to ray Y.

4. Taking B as centre, construct an arc of 3 cm which intersects ray BY at C.

5. Now join AC.

Therefore, triangle ABC is the required isosceles triangle.
