A coordinate point is the description of a location on the coordinate plane. Coordinate points are commonly written in the form (x, y) where x is the horizontal distance from the origin, and y is the vertical distance from the origin.
The coordinate plane is a grid formed by a horizontal number line and a vertical number line that cross at the (0, 0) point, called the origin. The coordinate plane is also called a Cartesian Plane.
Geometric patterns are visual patterns of geometric figures that follow a rule.
The image is the final appearance of a figure after a transformation operation.
A perpendicular bisector of a line segment passes through the midpoint of the line segment and intersects the line segment at .
Perpendicular lines are lines that intersect at a angle.
The pre-image is the original appearance of a figure in a transformation operation.
A reflection is a transformation that flips a figure on the coordinate plane across a given line without changing the shape or size of the figure.
A transformation moves a figure in some way on the coordinate plane.
A rigid transformation is a transformation that preserves distance and angles, it does not change the size or shape of the figure.
Learn to recognize reflections as flips and also lines of reflection.
