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 ...
Geometric Proof. Ensure you have: Pencil or pen. Guidance. Read each question carefully before you begin answering it. Check your answers seem right. Always show your workings. Revision for this topic. www.corbettmaths.com/more/further-maths/ ABC is an isosceles triangle. AB = BC ACD is a straight line. Angle BCD = x∘.
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.

Informal proof: LA = L C A + B = 180 degrees (supplementary angles) B + C = 180 degrees (supplementary angles) (substitution) Using postulates and math properties, we construct a sequence of logical steps to prove a theorem. I. A Straight Angle is 180 180 Il. Supplementary Angles add up to 180 m A+mLB=180 Example: 110 xyr and L ryz are
