This Problem Set is a part of the Lesson 15, Unit 7, Grade 6. Draw polygons in the coordinate plane given coordinates for the vertices; use coordinates to find the length of a side joining points with the same first coordinate or the same second coordinate. Let's use the coordinate plane to solve problems and puzzles. Learning targets: students can find the lengths of horizontal and vertical segments in the coordinate plane and plot polygons on the coordinate plane when students have the coordinates for the vertices.
