The sum of the angle measures of any triangle is 180 degrees. suppose that one triangle has a degree measure of 9x+2 and the other has a degree of 8x+1. write an expression for the degree measure of the third angle in the triangle.

The roots of the function f(x) = x2 – 2x – 3 are shown. what is the missing number?

Given: ae ≅ ce ; de ≅ be prove: abcd is a parallelogram. we have that ab || dc. by a similar argument used to prove that △aeb ≅ △ced, we can show that △ ≅ △ceb by. so, ∠cad ≅ ∠ by cpctc. therefore, ad || bc by the converse of the theorem. since both pair of opposite sides are parallel, quadrilateral abcd is a parallelogram.
