Answer 1

Answer:

We know that in an isosceles triangle base angles are equal.

(i) Draw a line segment BC = 4 cm.

(ii) At B and C, draw rays making an angle of 30° each intersecting each other at A.

∆ ABC is the required triangle.

On measuring the equal sides each is 2.5 cm (approx.) in length.

(ii) Steps of Construction :

We know that in an isosceles triangle, base angles are equal.

(i) Draw a line segment AB = 6.2 cm

(ii) At A and B, draw rays making an angle of 45° each which intersect each other at C.

∆ABC is the required triangle.

On measuring the equal sides, each is 4.3 cm (approx.) in length.
