- 1TransformationA change in the position, size, or shape of a figure or graph
- 2CongruentHaving the same size and shape
- 3Rotationa transformation about a point P, such that each point and its image are the same distance from P
- 4Center Of Rotationthe point about which a figure is rotated
- 5SymmetryIn the transformation of a figure such that the image coincides with the preimage, the image and preimage have symmetry
- 6Preimagethe original figure in a transformation
- 7Imagethe new position of a figure after a transformation
- 8Rigid MotionA transformation that does not change the size or shape of a figure.
- 9Translationa transformation that shifts or slides every point of a figure or graph the same distance in the same direction
- 10VectorA quantity that has magnitude and direction
- 11Initial Pointthe starting point of a vector
- 12Line Symmetrya figure that can be reflected across a line so that the image coincides with the preimage
- 13Line Of Symmetrya line that divides a plane figure into two congruent reflected halves
- 14Rotational Symmetrywhen a figure can be rotated about a point by an angle less than 360 degrees so that the image coincides with the preimage
- 15Angle Of Rotation Symmetrythe smallest angle through which a figure with rotational symmetry can be rotated to coincide with itself
- 16Terminal Pointthe ending point of a vector
- 17Angle Or RotationAn angle formed by a rotating ray, called the terminal side, and a stationary reference ray, called the initial side.
- 18ReflectionA transformation across a line, called the line of reflection, such that the line of reflection is the perpendicular bisector of each segment joining each point and its image.
- 19Perpendicular LinesLines that intersect to form right angles
- 20Perpendicular Bisector
