Finding Missing Vertices in Parallelograms

This video tutorial explains how to find missing vertices in polygons, using a rectangle and a parallelogram as examples. The instructor demonstrates how to extend lines to find the missing point in a rectangle and uses the concept of slope to determine the missing vertex in a parallelogram. The tutorial emphasizes precision over guessing and highlights the differences in approach between rectangles and parallelograms.

What is the main focus of this mini lesson?

• Drawing perfect circles

• Identifying types of polygons

• Calculating the area of polygons

• Finding missing vertices in polygons

Which two shapes are used as examples in the lesson?

• Circle and Ellipse

• Parallelogram and Rectangle

• Triangle and Square
