Unit 5 Coordinate Algebra Flashcards
acute angle
an angle measuring less than 90° but greater than 0°
angle
A figure created by two distinct rays that share a common endpoint (also known as a vertex).
angle of rotation
The amount of rotation (in degrees) of a figure about a fixed point such as the origin.
bisector
A point, line or line segment that divides a segment or angle into two equal parts.
circle
The set of all points equidistant from a point in a plane.
congruent
Having the same size, shape and measure.
corresponding angles
Angles that have the same relative position in geometric figures.
corresponding sides
Sides that have the same relative position in geometric figures
endpoint
The point at each end of a line segment or at the beginning of a ray.
image
The result of a transformation.
intersection
The point at which two or more lines intersect or cross.
isometry
a distance preserving map of a geometric figure to another location using a reflection, rotation or translation.
line
One of the undefined terms of geometry that represents an infinite set of points with no thickness and its length continues in two opposite directions indefinitely
line segment
A part of a line between two points on the line
line of symmetry
a line separating a figure into two halves that are mirror images.
