Someone just robbed a bank. the police set a triangular perimeter of 16 kilometers where the robber may be hiding. two of the three coordinates for this triangular perimeter are (2,2) and (-2,-1). the area covered is 12 square kilometers. which of the following is the third coordinate of the triangular perimeter?

a. (2,-4)
b. (-2,4)
c. (2,8)
d. (6, -4)

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

because that’s us why
