Question

answer it........not in short.........give full answer

Answer 1

Area of Δ ABC = 1/2 Base * altitude

= 1/2 AC * BE = 1/2 AB * CF = 1/2 AB * BE, given BE = CF

So AC = AB

Hence it is an isosceles Δ.

=================================

Consider the triangles ABE and ACF.

Angle A is common. angle BEA = 90 = angle CFA. The triangles are similar.

AB/BE = AC/CF,\ \ \ \ but BE = CF \\ \\ AB = AC

So isosceles triangle.
