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 ...

I can demonstrate knowledge skills, and reasoning ability of ALL previously learned material. ASSIGNMENT: Test #3 Grade: Assumptions and Justifications.
The following five steps are used to give geometric proofs: The Proof Process 1. Write the conjecture to be proven. 2. Draw a diagram if one is not provided. 3. State the given information and mark it on the diagram. 4. State the conclusion of the conjecture in terms of the diagram. 5. Plan your argument and prove your conjecture.
Given: ∠1 ≅ ∠3. Prove: ∠2 ≅ ∠4. 6. Given: ∠AEC is a right angle ∠BED is a right angle. Prove: ∠AEB ≅ ∠DEC. 7. Given: GE bisects ∠DGF. Prove: ∠1 ≅ ∠2. 8. If a pair of vertical angles are supplementary, what can we conclude about the angles? Sketch a diagram that supports your reasoning?
