An imaginary straight line used to describe the location of an object. Two or more axes are perpendicular to one another.
A figure formed by the group of points that are an equal distance from a shared point, or center.
In a right triangle, the ratio of the length of the side adjacent to the angle divided by the hypotenuse.
The distance from one edge of the circle to the opposite edge that passes through the center.
In a right triangle, the side located opposite the right angle.
Forming right angles at the intersection of two lines.

The distance from the center of a circle to a point on its circumference.
A triangle containing one angle that measures exactly 90 degrees.
In a right triangle, the ratio of the length of the side opposite the angle divided by the hypotenuse.
In a right triangle, the ratio of the length of the side opposite the angle divided by the adjacent side.
A three-sided figure determined by connecting three points that do not share the same line.
A ratio that describes a relationship between a side and angle of a triangle.
The branch of mathematics that addresses the measurements and relationships of a triangle and its parts.
