Lesson 1.4 (Part 1) Notes:

Perimeter and Area on a Coordinate Plane

This video introduces polygons, naming polygons, convex/concave polygons, and how to find the perimeter and area of triangles, rectangles and squares.


Lesson 1.4 (Part 2) Practice:

Perimeter and Area on a Coordinate Plane

I solve additional practice problems to accompany the notes video on the perimeter and area of triangles, squares, and rectangles on the coordinate plane.
