In an isosceles triangle ABC, points k and m are the midpoints of the lateral sides AB and BC, BD is the medina of the triangle. prove that triangle BKD = triangle BMD.
ВD – median, height and bisector of angle В (according to the property of an isosceles triangle).
Triangles BKD and BMD are equal in two sides and the angle between them (k and m are the midpoints of the sides (AB and BC) of an isosceles triangle, so AK = KB = BM = MC, BD is the common side of triangles BKD and BMD).
