Determining if a set of points makes a parallelogram or not

The video tutorial guides students through determining if a shape is a parallelogram using the slope formula. It emphasizes the importance of plotting and labeling points, calculating slopes for opposite sides, and verifying parallelism. The tutorial concludes that the given shape is not a parallelogram due to non-parallel opposite sides.

What is the first step to determine if a shape is a parallelogram?

Explain the slope formula used to determine if two sides of a parallelogram are parallel.

What characteristics must opposite sides of a parallelogram have?

How do you confirm that two sides are parallel using the slope formula?

If two sides are not parallel, what conclusion can you draw about the shape?
