- Multiplication property
- If a = b, then ac = bc
- Constructions
- drawings made with just a straightedge and compass.
- Two dimensional coordinate system
- has two axes (x and y) to create a coordinate plane
- Measure of an angle
- to every ray there corresponds a real number measured in degrees
- Origin
- starting point on a graph or number line also known as 0; the point of intersection of coordinate axes, where the value of the coordinates are all zero.
- Substitution property
- If a = b, then a can be substituted for b in any expression
- One dimensional coordinate system
- a number line
- X-axis
- horizontal axis on two dimensional coordinate system
- Y-axis
- vertical axis on two dimensional coordinate system
- Coordinate
- location of a point on a line or a plane, often written as [x,y]
- Degree
- unit used to measure angles
- Quadrant
- one of four divisions of plane created by axes
- One dimensional distance formula
- D = |x1 -x2|
- Coordinate
- location of a point in a plane in the form (x, y)
- Reflexive property
- a = a [any # is equal to itself)
- Division property
- If a = b and c doesn't = 0, then a/c = b/c
- Addition property
- If a = b, then a + c = b + c
- Three dimensional coordinate system
- has three axes (x, y, and z)
- Subtraction property
- If a = b, then a - c = b - c
- Distance
- to every pair of points on the line there corresponds a real number (real number is distance)
