Step-by-step explanation:

If BD is an altitude, it splits triangle ABC into 2 triangles.  It is also a median, so it splits the angle ABC into 2 congruent angles.  Angle ABD and CBD are congruent.  That means that angles A and C are congruent. This is true because the 2 angles at D are both right angles.  Because of this, side AB and side CB are congruent.  That means that this is an isosceles triangle.
