-----------------------------
acute angle = an angle that measures less than 90°
acute triangle = a triangle with every angle that measures less than 90°
adjacent angles = two angles that have the same vertex, share one side, and do not overlap
angle = two rays connected by a vertex
arc = a curved section of a circle
area = the number of square units inside a shape
bisect = divide into two equal parts
central angle = an angle formed by an arc in a circle
chord= a line segment that goes through a circle, with its endpoints on the circle
circumference = the distance around a circle
complementary angles = two angles whose sum is 90°
congruent = identical in shape and size
coordinate plane = a grid divided into four quadrants by both a horizontal x-axis and a vertical y-axis
coordinate points = points located on a coordinate plane
diagonal = a line segment between two non-adjacent vertices of a polygon
origin = coordinate point (0,0): the point on a coordinate plane at which the x-axis and y-axis intersect
parallel lines = two lines in a plane that do not intersect. Parallel lines are marked by a symbol ||.
parallelogram = a quadrilateral with two pairs of parallel sides
perimeter = the distance around a figure
perpendicular lines = lines that intersect to form right angles
polygon = a closed figure with three or more sides
Pythagorean theorem the formula a²+b²=c², where a and b represent the lengths of the
legs and c represents the length of the hypotenuse of a right triangle
Pythagorean triple = a set of three whole numbers that satisfies the Pythagorean theorem,
a²+b²=c², such as 3:4:5 and 5:12:13
quadrilateral = a four-sided polygon
radius = a line segment inside a circle with one point on the radius and the other point at
the center on the circle. The radius is half the diameter. This term can also be
used to refer to the length of such a line segment. The plural of radius is radii.
ray = half of a line. A ray has one endpoint and continues infinitely in one direction.

rectangle = a parallelogram with four right angles
diameter = a chord that passes through the center of a circle—the longest line you can draw
in a circle. The term is used not only for this line segment, but also for its length.
equiangular polygon = a polygon with all angles of equal measure
equidistant = the same distance
equilateral triangle = a triangle with three equal sides and three equal angles
exterior angle = an angle on the outer sides of two lines cut by a transversal; or, an angle outside
a triangle
hypotenuse = the longest leg of a right triangle. The hypotenuse is always opposite the right
angle in a right triangle.
interior angle = an angle on the inner sides of two lines cut by a transversal
