What is a point?
It is an exact location, that has no shape or size. Often depicted as a dot on a graph. Used to communicate the location of an object, or connections between other objects.
Point K is on line segment JL. Given JL=17 and KL=6, determine the length JK.
JK = 11
Find the midpoint of the segment with the following endpoints.
(−7,9) and (−4,6)
Midpoint: (−5.5 , 7.5)

(5,0) and (2,4)
5 units
What is Mx. Barbosa's favorite color?
Yellow
What is the difference between a line, a line segment, and a ray?
A line segment has two distinct end points, a ray has one end point and extends in the other directing forever, a line extends in opposite directs forever and ever.
Point L is on line segment KM. Given KL=5x−2, LM=4x−3, and KM=4x, determine the numerical length of LM.
x = 1 and LM = 1

What is colinear?
Points that exist on the same line.
Fun Fact: Any 2 points are colinear

What is coplanar? How do you name a plane?
Three or more points that create a boundless space. Often depicted as a shaded rectangle.
You need to three non-colinear points
Fun Fact: You can create a plane through any three points as long as one of the points is not on the same line as the other two!
