Unit 6: Is There a Point to This?

• This unit focuses on the concepts related to coordinate geometry. A system of geometry where the position of points on the plane is described using an ordered pair of numbers.
• Recall that a plane is a flat surface that goes on forever in both directions. If we were to place a point on the plane, coordinate geometry gives us a way to describe exactly where it is by using two numbers.
• In coordinate geometry, points are placed on the 'coordinate plane' as shown below. It has two scales - one running across the plane called the 'x axis. (These can be thought of as similar to the column and row in the paragraph above.) The point where the axes cross is called the origin and is where both x and y are zero.

Geometry and Spatial Sense

• Understand geometric concepts such as perpendicularity, parallelism, congruency, reflections, symmetry, and transformations including flips, slides, turns, enlargements, and rotations.
• Using a rectangular coordinate system (graph), apply and algebraically verify properties of two-dimensional figures, including distance, midpoint, slope, parallelism, and perpendicularity.
