Student could draw three angles such that ∠1 and ∠2 are complementary and ∠1 and ∠3 are complementary. 12. Answers vary depending on the picture. Possible answer: I∠1+ I∠2=90° and I∠1+ I∠3= 90°. 13. Statements Reasons This is a worksheet for segment and angle proofs. There are: 4 segment proofs 3 angle proofs 1 algebraic proof I gave this to students who wanted extra practice before the exam. Answer key is included, but be cautious of Substitution vs. Transitive (some Geometry teachers have different perspectives on these properties when they're used in proofs!)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 )
