Geometric Transformations REVIEW

Front

What is a geometric transformation?

Back

A geometric transformation is an operation that moves or changes a shape in a specific way, including translations, rotations, reflections, and dilations.

Front

Define translation in geometry.

Back

Translation is a type of transformation that slides a figure in a straight line from one position to another without changing its size, shape, or orientation.

Front

What is a rotation in geometry?

Back

A rotation is a transformation that turns a figure around a fixed point, known as the center of rotation, by a specified angle.

Front

What is reflection in geometry?

Back

Reflection is a transformation that flips a figure over a line, creating a mirror image of the original figure.

Front

What does it mean for a shape to have rotational symmetry?

Back

A shape has rotational symmetry if it can be rotated around a central point and still look the same at certain angles.

Front

How do you determine the angle of rotation for a shape?

Back

The angle of rotation is determined by how far the shape is turned around the center of rotation, measured in degrees.

Front

What is the line of symmetry?

Back

A line of symmetry is a line that divides a shape into two identical halves that are mirror images of each other.

Front

How many lines of symmetry does a regular hexagon have?

Back

A regular hexagon has 6 lines of symmetry.

Front

What is the result of a 90° clockwise rotation of a point (x, y)?

Back

The result of a 90° clockwise rotation of a point (x, y) is (y, -x).

Front

What is the result of a 180° rotation of a point (x, y)?

Back

The result of a 180° rotation of a point (x, y) is (-x, -y).
