Angle Relationships
Half of a straight angle. This angle measures exactly 90 degrees.
Right Angle
This is the point where two rays meet to form an angle.
Vertex
Any movement that changes the position or orientation of a figure.
Transformation
This direction moves the same way the hands of a clock move.
Clockwise
These angles are formed when two lines intersect and are always equal in measure.
Vertical Angles
This is the figure that results after a transformation
Image
This transformation slides a figure without turning or flipping it.
Translation
This direction moves opposite the way the hands of a clock move.
Counterclockwise
These angles are in matching positions when a transversal crosses two parallel lines.
Corresponding Angles
This system uses an x-axis and y-axis to locate points.
Coordinate Plane
This transformation flips a figure across a line.
Reflection
This is a pattern that covers a plane with no gaps or overlaps
Tessellation
These angles are on opposite sides of a transversal and between two parallel lines.
Alternate Interior Angles
This is a line that crosses two or more lines at different points.
Transversal
This transformation turns a figure around a fixed point.
Rotation
This is used to describe exactly where a figure moves during a transformation.
Coordinate Plane
This angle forms a straight line and measures 180 degrees.
Straight Angle
Two figures with the same shape and size are described by this word.
Congruent
This type of transformation keeps the shape and size the same.
Rigid Transformation
This involves performing more than one transformation in a specific order.
