It's your turn to practice using rotational and reflectional symmetry. Remember, some figures might have both. Work through the following flashcards answering the questions on the front, then flip each card over to check your work.
How many lines of symmetry does the figure above have? Draw them.
This image is of a kite. A kite has only one line of symmetry, like the one drawn above.
What is the rotational angle of the image above? Explain your reasoning.
This figure is a regular octagon. An octagon has an angle of rotation equal to 45°. Since there are 8 vertices, we can take 360° and divide by 8 to calculate an angle of rotation of 45°.
How many lines of symmetry does this figure have? Draw them.
This letter H has two lines of symmetry. They are drawn above.
Does this figure have both rotational and reflectional symmetry? If yes, what is the angle of rotation, and how many lines of symmetry does the figure have? Draw them.
This figure does have both rotational and reflectional symmetry. Notice the four lines of reflection drawn above. Also, this figure has a rotational angle of 90°.
