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 in determining if a set of points forms a parallelogram?

• Calculate the area of the shape

• Plot the points and label them

• Find the midpoint of each side

• Check if all angles are right angles

Which formula is used to determine if sides are parallel in a parallelogram?

• Distance formula

• Slope formula

• Area formula

• Midpoint formula

What are the coordinates of point D in the given problem?

• (0, 5)

• (5, 0)

• (1, -2)

• (-6, 4)

If the slope of side DC is 3/2, what is the slope of side AB?

• 5/3

• 1/2

• -9/5

• 3/2

What conclusion can be drawn if opposite sides of a quadrilateral are not parallel?

• The shape is not a parallelogram

• The shape is a square

• The shape is a rectangle

• The shape is a parallelogram
