In the given triangle ABC, angle A is 90° and segment AD is perpendicular to segment BC. A
B
С
Which of these could be a step to prove that BC2 = AB2 + AC2? (6 points)
O By the addition property of equality, Ac? plus AD2 = AB multiplied by DC plus AD2.
O By the addition property of equality, ACplus AD2 = BC multiplied by DC plus AD2.
By the addition property of equality, AC2 plus AB2 = AB multiplied by DC plus AB2.
O By the addition property of equality, AC2 plus ABP = BC multiplied by DC plus AB2.

step-by-step explanation:

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc
