Introduction to proofs: Identifying geometry theorems and postulates C congruent ? Explain using geometry concepts and theorems: 1) Why is the triangle isosceles? 2) Why is an altitude? 3) Why are the triangles congruent? 4) Why is NM a median? 5) If ABCD is a parallelogram, why are LA and 6) Why are the triangles congruent?
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 supplementary angles. And, although they are not adjacent, LS and xyr are supplementary as well. B

Theorems and postulates are not always reversible. For example, True or False: If two angles are right angles, then they are congruent. The converse statement, True or False: If two angles are congruent, then they are right angles.
If c2 > a2 + b2, then ABC is an obtuse triangle. If c2 < a2 + b2, then ABC is acute. 45 ̊-45 ̊-90 ̊ Triangle Theorem. In a 45 ̊-45 ̊-90 ̊ triangle, both legs are congruent, and the length of the hypotenuse is the length of a length times the square root of 2. 30 ̊-60 ̊-90 ̊ Triangle Theorem.
