What is a flip.
What is a slide.
A rotation is what kind of move (when performed on a shape)?
What is a turn.
What is the measure of a circle that connects the center to a point on the edge?
What is a radius.
lines that intersect to form a right angle
What is perpendicular
What is the main component that you need in order to perform a reflection?
What is the line of reflection.

What are parallel lines?
What are the terms associated with the direction of the rotation?
What are clockwise and counterclockwise.
What is the name of the figure AFTER it is transformed?
What is the image.
What is the term for a transformation that preserves the size and shape of a figure?
What is a rigid transformation.
What types of lines do you need to construct when performing a reflection?
What are perpendicular lines.
What information do you need on order to precisely translate a figure?
What is the distance and direction.
What is the term for the fixed point around which you rotate a figure?
What is the center of rotation.
What is the term for a figure BEFORE it is transformed?
What is pre-image.
This term describes a polygon that is built inside a circle.
What is inscribed.
What shape do you need to construct in order to ensure your pre-image and image points are exactly equidistant to the line of reflection?
What are circles.
What tool do you need in order to ensure you are moving each point the same distance in a translation?
What is the compass tool.
What are the three pieces of information that are needed to perform a rotation precisely?
What are: center of rotation, direction, and degrees.
What is the name for the vertices and sides of an image and pre-image that "match up" to each other after a transformation is performed.
What are corresponding parts.
This is a construction made by connecting the intersection points of 2 circles and cuts the shared radius into 2 equal parts.
