Front

What is the relationship between symmetry and balance in shapes?

Back

Symmetry often indicates balance in shapes, as symmetrical shapes appear evenly distributed around a central line.

Front

How can you determine if a shape is symmetrical?

Back

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

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.
