What is line symmetry?

Back

Line symmetry, also known as reflectional symmetry, occurs when a figure can be divided into two identical halves that are mirror images of each other along a line.

Front

What is point symmetry?

Back

Point symmetry exists when every part of a figure has a matching part at an equal distance from a central point, meaning the figure looks the same when rotated 180 degrees around that point.

Which letters of the alphabet have vertical line symmetry?

Back

The letters A, H, I, M, O, T, U, V, W, X, and Y have vertical line symmetry.

Front

Which letters of the alphabet have horizontal line symmetry?

Back

The letters B, C, D, E, H, I, O, X have horizontal line symmetry.

Front

What is rotational symmetry?

Back

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

Front

How can you determine if a shape has line symmetry?

Back

To determine if a shape has line symmetry, you can draw a line through the shape and see if the two halves are mirror images of each other.

Front

What is an example of a shape with both line and rotational symmetry?

Back

A circle has both line symmetry (infinite lines of symmetry) and rotational symmetry (it looks the same at any angle of rotation).

Front

What is the difference between line symmetry and rotational symmetry?

Back

Line symmetry involves dividing a shape into mirror-image halves, while rotational symmetry involves rotating a shape around a point and having it look the same at certain angles.

Front

Can a shape have rotational symmetry without line symmetry?

Back

Yes, a shape can have rotational symmetry without line symmetry, such as the letter Z, which has rotational symmetry but no line symmetry.

Front

What does it mean for a figure to be symmetrical?

Back

A figure is symmetrical if it can be divided into parts that are arranged in a balanced and proportional manner, either through line symmetry or rotational symmetry.
