Traverse through this huge assortment of transversal worksheets to acquaint 7th grade, 8th grade, and high school students with the properties of several angle pairs like the alternate angles, corresponding angles, same-side angles, etc., formed when a transversal cuts a pair of parallel lines. If a ray bisects an angle, then it divides the angle into 2 congruent angles. The idea of a proof is to make a universal statement – for example, you don’t just want to say that the angles in some triangles add up to 180\degree, you want to say that the angles in all triangles add up to 180\degree.This is a proof you actually do have to know, and you can see it here ( interior and exterior angles revision ).
