   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 ...

   Procedure for Detour Proofs 1. Determine which triangles you must prove congruent to reach the desired conclusion 2. Attempt to prove those triangles congruent – if you cannot due to a lack of information – it’s time to take a detour… 3. Find a different pair of triangles congruent based on the given information 4.

   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. Mark the diagram and answer the questions about the following proof.
