Unit 6  Coordinate Planes
Learning Outcomes:
Identify and label the axes, origin, and quadrants of the coordinate plane. Graph ordered pairs on a coordinate plane. Draw polygons in the coordinate plane. Determine the length of a side of polygon by using the coordinates. Identify regular polygons. Draw lines of symmetry to divide regular polygons into two congruent parts. Determine the congruence of segments, angles, and polygons. Determine whether polygons are congruent or noncongruent. 
Essential Questions:
Why are there established rules of arithmetic to help solve problems? How can you use geometric components and/or figures to create new figures? What relationship is there between the ordered pairs on horizontal and vertical line segments?

coordinaate plane

A twodimensional surface by two intersecting and perpendicular number lines on which points are plotted and located by their x and y coordinates.

Origin
ordered pair

The point on the coordinate plane that is (0,0) or the middle of the grid.
A pair of numbers used to locate a point on a coordinate plane is called an ordered pair. An ordered pair is written in the form (x, y) where x is the xcoordinate and y is the ycoordinate.
