Basics
The measure of a right angle
What is 90 degrees?
Pair of angles that add up to 180
What are supplementary angles?
The longest side of a triangle
What is a hypotenuse?
When a shape is just slid in a different direction across the graph
What is a translation?
Opposite sides are equal in length and parallel, opposite angles are equal, diagonals bisect each other (cut each other in half)
What is a parallelogram?
A set of points that extends infinitely in both directions
What is a line?
Pair of angles that add up to 90
What are complementary?
The side of the triangle across from the angle of perspective
What is the opposite?
When a shape is magnified or shrunk
What is a dilation?
All four angles are right angles, diagonals are equal in length and bisect each other
What is a rectangle?
An exact location in space with no dimension, size, or length
What is a point?
A line that splits an angle directly and evenly down the middle
What is an angle bisector?
The side of the triangle that isn't the opposite or the hypotenuse
What is the adjacent?
When a shape is flipped over an axis
What is a reflection?
All four sides are equal in length, and all four angles are 90 degrees, diagonals are equal, and they bisect each other at perfect right angles
What is a square?
A finite, measurable portion of a line with two distinct endpoints
What is a line segment?
Angle A and Angle B are supplementary. If Angle A measures 55 degrees, what is the measure of Angle B?
What is 125 degrees?
The angle marked by the Greek letter Theta
What is the angle of perspective?
When a shape is spun around
What is a rotation?
Has two separate pairs of adjacent sides that are equal in length, diagonals intersect at right angles
What is a kite?
A straight path that begins at a single endpoint and extends infinitely in one direction.
What is a ray?
If Angle A and Angle B are vertical angles, and Angle A measures 45 degrees, what is the measure of Angle B?
What is 45 degrees?
The three ratios represented by SOH CAH TOA
What you do to the coordinates when something is reflected over the origin OR rotated 180 degrees
What is "make the coordinates opposite"?
Has exactly one pair of opposite sides that are parallel.
What is a trapezoid?
