Sure! Here are the definitions for each term used in your lessons:
-
Line of Symmetry - A line that divides a figure into two mirror-image halves.
-
Reflection - A transformation that creates a mirror image of a shape over a line (the line of reflection).
-
Rotation - A transformation that turns a shape around a fixed point by a certain angle (degree of rotation).
-
Transformation - A process that moves or changes a shape into a different position or size.
-
Dilation - A transformation that alters the size of a shape but maintains its proportions, using a scale factor.
-
Pre Image - The original shape before any transformation is applied.
-
Image - The resulting shape after a transformation has been applied to a pre-image.
-
Shrink - A type of dilation that reduces the size of a shape.
-
Degree of rotation - The measure of how far a shape is rotated around the center point.
-
Clockwise - The direction of rotation that moves in the same direction as the hands of a clock.
-
Scale Factor - A number that describes how much a shape is enlarged or reduced during a dilation.
-
Translation - A transformation that slides a shape in a straight line from one position to another without changing its size or orientation.
-
Enlargement/Expansion - A type of dilation that increases the size of a shape.
