Chapter 4 Answer Key– Reasoning and Proof CK-12 Geometry Honors Concepts 7 10. 11. Answers vary. 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 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 )Name: Level 2 Further Maths Ensure you have: Pencil or pen Guidance 1. Read each question carefully before you begin answering it. 2. Check your answers seem right.opposite angles are congruent. What is the reason justifying that ∠B ≅∠D? 1) Opposite angles in a quadrilateral are congruent. 2) Parallel lines have congruent corresponding angles. 3) Corresponding parts of congruent triangles are congruent. 4) Alternate interior angles in congruent triangles are congruent. Because we've shown that if x is equal to y, there's no way for l and m to be two different lines and for them not to be parallel. And so we have proven our statement. So now we go in both ways. If lines are parallel, corresponding angles are equal. If corresponding angles are equal, then the lines are parallel. 7.Created by. KMillMath. This product contains two proofs where the objective is to prove angle relationships using Corresponding Angles, Alternate Interior Angles, and Supplementary Angles given that lines are parallel. There is an answer key included, but please keep in mind that proofs can be completed in multiple ways.
