प्रश्न

Construct a triangle ABC in which AB = AC = 5 cm and BC = 5.6 cm. If possible, draw its lines of symmetry.

आकृति

उत्तर

Steps of Construction:

(i) Draw a line segment BC = 5.6 cm

(ii) With centres B and C and radius 5 cm, draw two arcs intersecting each other at A.

(iii) Join AB and AC.
∆ ABC is an isosceles triangle.

(iv) Draw the bisector of ∠A. This is the only one line of symmetry as the triangle is an isosceles.
