Write an indirect proof to show that opposite sides of a parallelogram are congruent. be sure to create and name the appropriate geometric figures.

So the problem ask to find an indirect proof to show that opposite sides of a parallelogram are congruent. So if we want to prove that a rectangle has a vertexes of ABCD where as to prove that AB=CD, lets start by proving it using AB is not equal to CD nad forming a parallelogram and the lines that bisect each side can prove that AB=CD

Hello! i hope this
since the cosine is the ratio of the adjacent side to the hypotenuse, you can see that cos 60° = ½. answer. according to the property of cofunctions (topic 3), sin 30° is equal to cos 60°. sin 30° = ½.
