Proof definition
A proof is a logical argument that uses deductive reasoning to show that a statement is true
What is the inverse of this statement: If I set my alarm, then I will make it to school on time.
If I don't set my alarm, then I won't make it to school on time.
Name this postulate: ab + bc = ac
Segment Addition Postulate

How can you prove a mathematical statement
starting with a given, use logic and deductive reasoning backed with evidence to come to a conclusion
Define both angle and segment
angle - the space (usually measured in degrees) between two intersecting lines or surfaces at or close to the point where they meet.
segment - a geometric figure, part of line, with two endpoints
What is the contrapositive of this statement: If a shape is a square, then it has four equal sides.
If a shape doesn't have four equal sides, then it is not a square.
Name this postulate: measure of angle a + measure of angle b = measure of angle c
Angle addition postulate
