G.2 pt. 3 Reflectional & Rotational Symmetry Assessment

Front

What is the angle of rotational symmetry when the order is 10?

Back

36°

Front

Which of the following shapes show a line of symmetry?

Back

Shapes with at least one line of symmetry include: circle, square, rectangle.

Front

Which of the following shapes does not have a line of symmetry?

Back

Shapes like a scalene triangle do not have any lines of symmetry.

Front

How many lines of symmetry does a regular octagon have?

Back

8 lines of symmetry.

Front

How many lines of symmetry does a triangle have?

Back

A triangle can have 1, 2, or 3 lines of symmetry depending on its type.

Front

What is rotational symmetry?

Back

Rotational symmetry is when a shape can be rotated around a center 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 shape fits onto itself during a full rotation of 360°.

Front

How do you calculate the angle of rotational symmetry?

Back

Angle of rotational symmetry = 360° / order of rotational symmetry.

Front

What is a line of symmetry?

Back

A line of symmetry is a line that divides a shape into two identical parts.

Front

Can a shape have more than one line of symmetry?

Back

Yes, shapes like squares and circles can have multiple lines of symmetry.
