Angle Relationships

100

Half of a straight angle. This angle measures exactly 90 degrees.

Right Angle

200

These angles are formed when two lines intersect and are always equal in measure.

Vertical Angles

300

These angles are in matching positions when a transversal crosses two parallel lines.

Corresponding Angles

400

These angles are on opposite sides of a transversal and between two parallel lines.

Alternate Interior Angles

500

This angle forms a straight line and measures 180 degrees.

Straight Angle

Parts of Angles & Position

100

This is the point where two rays meet to form an angle.

Vertex

200

This is the figure that results after a transformation

Image

300

This system uses an x-axis and y-axis to locate points.

Coordinate Plane

400

This is a line that crosses two or more lines at different points.

Transversal

500

Two figures with the same shape and size are described by this word.

Congruent

Transformations

100

Any movement that changes the position or orientation of a figure.

Transformation

200

This transformation slides a figure without turning or flipping it.

Translation

300

This transformation flips a figure across a line.

Reflection

400

This transformation turns a figure around a fixed point.

Rotation

500

This type of transformation keeps the shape and size the same.

Rigid Transformation

Movement & Direction

100

This direction moves the same way the hands of a clock move.

Clockwise

200

This direction moves opposite the way the hands of a clock move.

Counterclockwise

300

This is a pattern that covers a plane with no gaps or overlaps

Tessellation

400

This is used to describe exactly where a figure moves during a transformation.

Coordinate Plane

500

This involves performing more than one transformation in a specific order.

Sequence of transformations
