Theorem: Let ABC be an isosceles triangle with AB = AC. ... This can't be quite
deduced from the B&B form of the axioms. ... AMB = angle AMC = right angle (so
line MA is the perpendicular bisector of BC and also the altitude of ABC through
A).

AN ISOSCELES RIGHT TRIANGLE is one of two special triangles. (The other is
the 30°-60°-90° triangle.) The student should know the ratios of the sides.
