LINE SYMMETRY
1.  Complete this information:  The most common type of symmetry is line symmetry. A figure is said to have line symmetry if :

2.  Another name for line symmetry is:  ____________________________________________

3.  At the bottom of the line symmetry page, click on the letters activity and record your answers below.  Assume that the letters will be block letters and not any fancy font.  Which letters have line symmetry? Mark where the line of symmetry is on the letters.

4. HOMEWORK:  find a picture of something that has line symmetry or draw  a picture of something with line symmetry.  Mark where the line of symmetry is on the picture.

ROTATIONAL SYMMETRY:

5.  Complete this information:  A figure is said to have rotational symmetry if :

6.  Another name for rotational symmetry is: ______________________________________________

7.  How could you describe the center of rotation and where would you find it in something that has rotational symmetry?

8.How do you calculate the magnitude of rotation of a figure with rotational symmetry?

9.  How do you find the order of rotation?

10.  At the bottom of the rotational  symmetry page, click on the HubCap activity and record your answers below. 

11.  HOMEWORK:  find a picture of something that has rotational symmetry or draw  a picture of something with rotational symmetry.  a)  Mark the center of rotation, b)  find its magnitude and c)  find its order.

POINT SYMMETRY:

12.   Complete this information:  A figure is said to have point symmetry if :

13.  Point symmetry is a type of _________________________ symmetry.

14.  How do you know if an object has point symmetry if all you know about the object is that it has rotational symmetry and you know it’s order?

15.  At the bottom of the point symmetry page, click on the Cards activity and record your answers below.
Put an x in the box of the cards with point symmetry.

15.  HOMEWORK:  find a picture of something that has point symmetry or draw a picture of something with point symmetry.  Mark the center of rotation, show  its magnitude and order.
