Midpoint and Distance in the Coordinate Plane
The midpoint of a line segment curs the segment into two congruent halves. If a segment has endpoints with coordinates (x1, y1) and (x2, y2), then we can find the coordinates of a midpoint by using the midpoint formula located on the left. Watch the video below to see the Midpoint Formula in action. Midpoint […]

Logic and Reasoning in Geometry
In this unit, we will learn the difference between inductive and deductive reasoning. You will make conjectures and learn how to verify them with the use of deductive reasoning. In addition to the various conditional statements, we will also explore biconditional statements. A conclusion based on a pattern is called a conjecture. A conjecture is a guess based on analyzing information or observing a […]

Points, Lines, and Planes
Space is a 3dimensional set of all points, lines, and planes. A point is a location. A line contains a series of points that extend forever in opposite directions. Points that lie on the same line are called collinear. A line has no thickness or width. There is exactly one line through any two points. The line can be named […]
