It takes Julie 15 minutes to put all of her son’s toys in the toy box. While she tries to put away his toys, her son is constantly pulling toys out of the toy box and putting them back on the floor. It takes him 20 minutes to empty the toy box by himself. How long will it take Julie to put away all the toys if her son keeps trying to pull them out?

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

what level of math? also i don't need to be paid if i can you.
