QUESTIONS AND ANSWERS

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 line that touches a circle at only one point. circle The set of all ...

line - answer-A straight one-dimensional figure that extends infinitely in both directions. perpendicular - answer-Describes lines intersecting each other to form a 90 degree, or right, angle. circle - answer-The set of all points that are equidistant from a point. radius - answer-The distance from the center of a circle or sphere to any point on the outer edge. isosceles trapezoid - answer-Quadrilateral with one pair of parallel opposite sides (the bases) and another pair of equal o...
