Ms. Martinez bought 11 1/4 yards of fabric to make identical costumes for all the members of the chorus in the school musical. Each costume used 2 1/4 yards of fabric. How many costumes did Ms. Martinez make?​

which expression represents the approximate length of bc?

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

final total: 63
