Transformations

Vertex

• A point where two or more edges meet.

• A type of angle in geometry.

• A line segment connecting two points.

• A shape with three sides.

Rigid Transformation

• A transformation that changes the size of a figure.

• A move that does not change any measurements of a figure.

• A transformation that only involves scaling.

• A move that distorts the shape of a figure.

Coordinate Plane

• A system for telling where points are.

• A type of graph used for statistics.

• A method for measuring angles.

• A technique for drawing shapes.

Rotation

• A rotation moves every point on a figure around a center by a given angle in a specific direction.

• A rotation flips a figure over a line to create a mirror image.

• A rotation enlarges a figure by a certain scale factor.

• A rotation translates a figure to a different location without changing its orientation.

Translation

• A translation rotates a figure around a point.

• A translation moves every point in a figure a given distance in a given direction.

• A translation reflects a figure over a line.

• A translation scales a figure to a different size.

Corresponding

• When two figures are identical in size and shape.

• When part of an original figure matches up with part of a copy.

• When angles in two different figures are equal.

• When segments in two figures are parallel.

Counter-Clockwise

• To turn in the same direction as the hands of a clock.

• To turn opposite of the way the hands of a clock turn. The top turns to the left.

• To turn in a circular motion without changing direction.

• To turn only to the right.

Reflection

• A reflection across a line moves every point on a figure to a point directly on the opposite side of the line, maintaining the same distance from the line.

• A reflection across a line rotates the figure around the line by 180 degrees.

• A reflection across a line flips the figure upside down without changing its position.

• A reflection across a line stretches the figure away from the line.

Clockwise

• To turn in the opposite direction of the hands of a clock.

• To turn in the same direction as the hands of a clock. The top turns to the right.

• To turn in a circular motion without a specific direction.

• To turn only to the left side.

Transformation

• A transformation is a change in position or size of a shape.

• A transformation is a translation, rotation, reflection, or dilation, or a combination of these.

• A transformation is a method to calculate the area of a shape.

• A transformation is a process of converting 2D shapes into 3D shapes.
