WARM UP FEBRUARY 5, 2014 1.What is the scale factor of the line AB? A(4,8) B(3, 9) A(2, 4) B(3/2, 9/2) 2. What two transformations create a glide reflection?

3
EOCT The points (0,1), (1,5), (2, 25), (3, 125) are on the graph of a function. Which equation represents that function?

QUIZ

5
Symmetry A figure has symmetry if a transformation occurs and the image coincides with the preimage. There are two types of symmetry which we will look at line symmetry and rotational symmetry.

7
LINE SYMMETRY A figure has line symmetry if it can be reflected across a line so that the image coincides with the preimage. The line of symmetry is the line that divides the figure into two congruent halves.

9
HOW MANY LINES OF SYMMETRY?

Rotational Symmetry All 2 dimensional shapes have some rotational symmetry. The degree of rotational symmetry that an object has is known as its order. Order 1 Order 2 Order 3 Order 4 For shapes that have order 2 rotational symmetry or higher, a single centre of rotation can be located. For shapes that have only order 1 rotational symmetry a centre of rotation can be found anywhere within it. The order of rotational symmetry that an object has is the number of times that it fits on to itself during a full rotation of 360 degrees.
