Aplummer is fixing a pipe with an interior diameter of 0.63 inches. he buys a replacement pipe that must fit inside the old pipe. he uses plumbing tape that will fill 0.15 inches off the space between the two pieces of pipe. the new pipe must be 0.1 inches smaller than the old pipe and tape so that it can fit inside. what is the largest interior diameter pipe he can buy that will still fit inside the old pipe?

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
