Question

ABC is right - angled triangle in which ∆A= 90° and AB=AC. Fine ∆B and ∆C​

Answer 1

Answer:

The first way that we can prove that triangle ABC is a right triangle is by proving that there is a one and only one right angle in the triangle. In order to prove that this shape has a right angle, we must prove that two of the slopes are negative reciprocals (the fraction is flipped and negated).
