Polygon : is a closed figure with no rounded sides
Quadrilateral : a closed figure with only 4 sides
Plane(not an airplane) : a flat surface that can go on forever
PI : 3.14 (it has more numbers but this is the number we mainly use)
Perimeter : the amount of space around a shape measured in linear units
Area : the amount of space inside a shape measured in squared units
Volume : the amount of space inside a 3D figure measured in cubic units
Point : marks an exact location in space
Line: endless and straight with no endpoints
Line segment : part of a line with two endpoints
Ray :a part of a line that goes on forever in one direction an has one endpoint
Parallel Lines : lines i a plane that never intersect and are equally distant at every point
Intersecting Lines : lines that cross or meet at one point
Perpendicular Lines : lines that intersect to form right angles
Inequality : a mathematical sentence that compares two unequal expressions using , less than, greater than, less than or equal to, greater than or equal to , and not equal
Mode : the number that appears most often in a group of numbers
Median: the middle number , when data is listed least to greatest
Range : the difference between the greatest number and the least
Mean : the average of all of your data , you add up all of the numbers then divide its by how many numbers you have
