Mathematics for Elementary Educators III - D127 Images included vertical line A line that runs up and down on the coordinate plane, parallel to the yaxis. It has no run, or change in x-value. complementary angles Two angles whose sum is equal to 90°. line A straight one-dimensional figure that extends infinitely in both directions. origin The point on a coordinate plane where the x-axis and y-axis intersect. Typically, the point represents 0 on both axes. tangent A straight...
