What is a line that consists of two points called endpoints and all the points lying between those two points?
Line Segment
200
What is inductive reasoning?
Process of observing data, recognizing patterns and making generalizations about these patterns
200

Linear pair conjecture
300
What is a line that has a beginning point and extends infinitely in one direction?

What is deductive reasoning?
The process of showing that certain statements follow from agreed upon assumptions and proven facts; helps to explain why your conjecture are true.

What is concurrent?
Three or more lines that intersect in the same spot.
400
What is the arc of a circle?
Two points on the circle and the continuous (unbroken) part of the circle between the two points.
500
What is the difference between a equilateral polygon and a equiangular polygon?
