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' and another a right angles to it called the y 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.
