As you all know, the exams are coming up soon.This is a review of all the things we've learned in Math this semester, so you better start studying.

You must know how to define:

Translation: a slide along a straight line.

Rotation: a turn around a fixed point.

Reflection: flip over a mirror line.

Remember: a mirror line can be anywhere, not only as an axis.

Make this shape: (0,0) (3,0) (3,8) (0,8)

Let's hope, you all remember what a coordinate grid is. If not, here's a review.

Cartesian Plain/Coordinate Grid: A vertical, up and down number line, that meets a horizontal number line.

x-horizontal number line

y- vertical number line.

Origin: where the x number line and y number line intersect.

Quadrants: The four regions on a coordinate grid.

Coordinates: the value of an ordered pair.

These are the quadrants on a coordinate grid(I hope you all know your roman numerals)

You must also be able to identify the signs of each quadrant:

Quadrant 1: (+,+)

Quadrant 2: (-,+)

Quadrant 3: (-,-)

Quadrant 4: (+,-)

Now that you know this, try to find which quadrant each letter is in and it's coordinates.

A- Quadrant 1 (3,1)

B- Quadrant 1 (1,3)

C- Quadrant 2 (-2,1)

D- Quadrant 3 (-1,-1)

E- Quadrant 4 (2,-2)

What is the horizontal and vertical movements of point C to E?

4 units horizontal (right)

3 units vertical (down)

Note: The Horizontal movement is always identified first.

Where is the mirror line?

A line intersecting the y axis at positive 1.
