In ΔABC, AB = AC and the bisector of ∠B and ∠C meet at a point O, then ΔOBC is
Scalene triangle
Eequilateral triangle
Congruent to ΔABC
Isosceles triangle
If ABC is a triangle , AB = AC,and AB = BC then ΔABC
A triangle of sides AB = 9.5 cm, BC = 4.3 cm and AC = 6.2 cm is constructed. Then △ABC is
In triangle ABC, altitude BE = altitude CF. Then triangle ABC is
Sides of a triangle ABC are equidistant from the centre O of its circumcircle. Triangle ABC is
