Symmetry, Composition of Transformations, and review

Front

What is line symmetry?

Back

Line symmetry occurs when a shape can be divided into two identical halves that are mirror images of each other.

Front

What is rotational symmetry?

Back

Rotational symmetry is when a shape can be rotated around a central point and still look the same at certain angles.

Front

What is the order of rotation?

Back

The order of rotation is the number of times a shape maps onto itself during a full rotation of 360 degrees.

Front

What is the smallest angle of rotation for a shape with order 6?

Back

60 degrees.

Front

How do you determine if a shape has line symmetry?

Back

To determine line symmetry, you can draw a line through the shape and see if both sides are mirror images.

Front

What is a transformation in geometry?

Back

A transformation is an operation that moves or changes a shape in some way, such as translation, rotation, or reflection.

Front

What is a reflection in geometry?

Back

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

Front

What is a translation in geometry?

Back

A translation is a transformation that moves a shape from one location to another without changing its size, shape, or orientation.

Front

What is the difference between a rotation and a reflection?

Back

A rotation turns a shape around a point, while a reflection flips it over a line.

Front

What is the sequence of transformations?

Back

The sequence of transformations is the order in which multiple transformations are applied to a shape.
