Pythagorean theorem
In a right triangle, the sum of each of the shortest sides squared equals
the longest side squared.
diameter
The distance from one side of a circle to the other side that passes
through the center point.
supplementary angles
Two angles whose sum is equal to 180°.
angle
,The amount of rotation (often measured in degrees) needed to make
one line segment, ray, or line identical with another line segment, ray,
or line.
parallel
Two lines, line segments, rays, or planes that are the same distance
from one another and never intersect.
trapezoid
Quadrilateral with one pair of parallel opposite sides.
x-axis
The horizontal line that passes through the origin on a coordinate
plane.
,arc
Angles greater than 180°.
degrees
The units in which angles are measured, denoted by the symbol °.
legs
The sides of a right triangle not opposite the right angle.
bisect
To divide into two equal parts.
right angle
An angle of 90°
, chord
A line segment that spans a circle. Each end of the line segment is on
the edge of the circle.
area
The amount of space inside a two-dimensional figure.
rectangle
Quadrilateral with four right angles, equal opposite sides, and two sets
of parallel opposite sides.
irregular polygon
A polygon whose sides are not all equal and whose angles have
different measures.
