In the figure, triangle ABC is an isosceles triangle with AB = AC and measure of angle ABC = 50o. Then the measure of angle BDC and angle BEC will be
ABC is a triangle in which altitudes BE and CF to sides AC and AB are equal (see the given figure). Show that
(i) △ABE≅△ACF
(ii) AB=AC, i.e., ABC is an isosceles triangle.
