ANW - Transformations on the Coordinate Plane

Front

What is a transformation in the coordinate plane?

Back

A transformation is an operation that moves or changes a shape in some way on the coordinate plane.

Front

What are the four main types of transformations?

Back

The four main types of transformations are translation, rotation, reflection, and dilation.

Front

Define translation in the context of transformations.

Back

Translation is a transformation that moves every point of a shape a constant distance in a specified direction.

Front

What is the rule for translating a point (x, y) to the right by 5 units?

Back

The rule is (x, y) --> (x + 5, y).

Front

What is the rule for translating a point (x, y) down by 3 units?

Back

The rule is (x, y) --> (x, y - 3).

Front

How do you find the new coordinates of a point after translation?

Back

Add the translation values to the original coordinates.

Front

What does it mean for a shape to have lines of symmetry?

Back

A shape has lines of symmetry if it can be divided into two identical halves that are mirror images of each other.

Front

How many lines of symmetry does a circle have?

Back

A circle has an infinite number of lines of symmetry.

Front

What is the effect of a reflection transformation?

Back

A reflection transformation flips a shape over a line, creating a mirror image.

Front

What is the rule for rotating a point 90 degrees counterclockwise around the origin?

Back

The rule is (x, y) --> (-y, x).
