Provide an appropriate response.Let ABC be an isosceles triangle with ?B ? ?C. Suppose that M is a point on BC such that 
is perpendicular to 
. Prove that M is the midpoint of 
.
What will be an ideal response?
Answers will vary. A sample correct response would be as follows.
AB = AC and clearly AM = AM. By AAS, ?AMB ? ?AMC, and so MB = MC, i.e. M is the midpoint of BC.
