Tom was saving $3000 for a trip. he initially deposited $200 in a savings account and then deposited a fixed amount every month in the account for the next 5 months. then he received a check in the mail. the check was three times as much as the total amount he had saved so far. when he deposited the check in his savings account, he had $200 more than he needed. what was the fixed amount he deposited in the savings account during the 5 months?

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
