Complete the following proof.

given: rectangle ruts

prove: ∠usr = ∠sut

There is a theorem that states that the two triangles made from connecting a rectangles opposing vertices produces two identical triangles. you can then use the cpctc theorem to prove the angles are congruent. it can also be proven by using the hypotenuse-leg theorem; US=SU because of the symmetric property, RU=ST because RUTS is a rectangle and therefore its parallel sides are congruent, ∠URS and ∠UST are right because RUTS is rectangular, therefore triangleUSR=triangleSUT because of the hypotenuse leg theorem, ∠USR=∠SUT becuase of CPCTC
