Understanding the Coordinate Plane and Geometry Concepts
Today, we will not have warmups due to an early release day. Instead, focus on your agenda and retrieve yesterday’s assignment from your Record & Practice Journal (RPJ), pages 23-4. Tear out page 26 of your RPJ. This lesson covers the coordinate plane, including how to describe the locations of points and answer geometry questions. We will review key concepts such as quadrants, axes, and the characteristics of ordered pairs, followed by geometry problems involving triangle vertices.

Presentation Transcript
9/12 • No warmups today (early release day). Instead: • Write your agenda. • Get out yesterday’s assignment (RPJ pgs. 23-4) • Get your Record & Practice Journal and tear out page 26. Put your RPJ back.
1.6: The Coordinate Plane Describing the Locations of Points And Answering Geometry Questions
Places on the coordinate Plane Name • Quadrant I • Quadrant II • Quadrant III • Quadrant IV • X-axis • Y-axis • Origin • Characteristics of Ordered Pair • (pos, pos) • (neg, pos) • (neg,neg) • (pos,neg) • (any, 0) • (0, any) • (0, 0)
Describe the location of each point. • (-3, 2) • (5, -12) • (7, 0) • (0, 0) • (-8, -15) • (0, -4) • (19, 24)
Geometry Problems: Example Two vertices of a triangle are shown. Which of the following points could be the location of the third vertex? • (-4, -3) • (0, -3) • (4, -3) • (-3, 4)
