About This Lesson
This lesson begins by using the coordinate plane to measure the length of several horizontal line segments. From that students are asked to look at what coordinate stays the same and what coordinate changes for each horizontal line segment. A relationship between the changing coordinate and the length of the line segment (previously found using last lesson’s method) is also discussed. Lesson Objective: Students will be able to use the coordinates of vertices to measure the lengths of any horizontal or vertical polygon side. Aligned to Common Core State Standard: 6.G.3
