Angle Relationships and Properties

Origin

• (0,0) on a coordinate plane

• (1,1) on a coordinate plane

• (-1,-1) on a coordinate plane

• (2,2) on a coordinate plane

X-axis

• The vertical line on a coordinate plane

• The horizontal line on a coordinate plane

• The line that represents the slope of a graph

• The line that divides the coordinate plane into quadrants

Vertical Line Test

• Drawing a vertical line on a graph to determine if the line is a function or not. If the vertical line touches one point, then it's a function.

• A method to find the slope of a line on a graph.

• A technique to measure the area under a curve.

• A way to identify the x-intercepts of a function.

Alternate interior angles

• angles that are supplementary to each other

• angles that are equal to 90 degrees

• angles in the same position in relation to the transversal and therefore congruent

• angles that are adjacent to each other
