प्रश्न
Construct a triangle ABC in which each side measures 5.8 cm. Draw all the possible lines of symmetry.
उत्तर
Steps of Construction :
(i) Draw a line segment BC = 5.8 cm.
(ii) With Band C as centre and radius = 5.8 cm, draw two arcs which intersect each other at A.
(iii) Join AB and AC. ABC is the required triangle.
(iv) Dr aw the bi sectors AD, BE and CF of L.A, L. Band L. C respectively.
Hence, AD, BE and CF are the lines of symmetry of trianQle ABC.
