Me answer

if triangle mnl is rotated 180° about point n, which additional transformation could determine if triangle onp and triangle mnl are similar by the aa similarity postulate?

a. reflect onp over line k

b. reflect m'n'l' over line k

c. dilate onp from point n by a scale factor of line np/ line nl

d. dilate m'n'l' from point n by a scale factor of line np / line nl

{¡ you so much! }

The answer is D, since you need to make it smaller by dilation, which means making the bigger triangle similar/same size as the other one.

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
