(As you probably know, congruent [symbolized by ≅] is a fancy word for “equal” or “same size.”) Congruent segments: Ditto, like for congruent angles. You can’t assume segments are the same size.The first one focuses on angles, the second on lines and angles. The third one puts it all together.

Proof. 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 )With the help of this worksheet on measuring angles students can practice questions based on the angles and understand the concept.
