Unit 5 Test

Front

What is rotational symmetry?

Back

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

Front

What is the order of rotational symmetry?

Back

The order of rotational symmetry is the number of times a figure matches its original position during a full rotation of 360 degrees.

Front

How many lines of symmetry does a butterfly have?

Back

A butterfly has 1 line of symmetry.

Front

How many lines of symmetry does a square have?

Back

A square has 4 lines of symmetry.

Front

Which letters have rotational symmetry?

Back

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

Front

What is a line of symmetry?

Back

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

Front

What transformation is a translation?

Back

A translation is a transformation that moves every point of a figure the same distance in the same direction.

Front

What is reflection in geometry?

Back

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

Front

What is rotation in geometry?

Back

Rotation is a transformation that turns a figure around a fixed point at a certain angle.

Front

What is dilation in geometry?

Back

Dilation is a transformation that changes the size of a figure but keeps its shape the same.
