Introduction to proofs: Identifying geometry theorems and postulates ANSWERS C congruent ? Explain using geometry concepts and theorems: 1) Why is the triangle isosceles? PR and PQ are radii of the circle. Therefore, they have the same length. A triangle with 2 sides of the same length is isosceles. 2) Why is an altitude? AB = AB (reflexive ...

Name Ways to Prove Triangles Congruent SSS (side, side, side) = three sides of one triangle congru- PROVING RECTANGLES USING COORDINATE GEOMETRY WAYS TO PROVE HOW ARE WE GOING TO DO THIS USING COORDINATE GEOMETRY? 1.) Prove that it is a PARALLELOGRAM with 2.) Prove that it is a PARALLELOGRM with 3.) Prove that all angles are Let’s pick a way and stick with it! - - 2.) Find the coordinates of E if CHER is a Rectangle C(0,2) H(4,8) E(x,y) R(3,0). One method of proving statements and conjectures, a paragraph proof, involves writing a paragraph to explain why a conjecture for a given situation is true. Paragraph proofs are also called informal proofs, although the term informal is not meant to imply that this form of proof is any less valid than any other type of proof.
