Understanding Quadrilaterals

The video tutorial guides students through plotting ordered pairs to form a quadrilateral, initially hypothesizing it as a rectangle. It demonstrates using slopes to check for right angles and applies the distance formula to verify side lengths. The conclusion is that the shape is a parallelogram, supported by mathematical evidence.

What is the first step in solving the problem of plotting ordered pairs to form a quadrilateral?

• Calculate the area of the quadrilateral

• Plot the points and label them

• Identify the type of quadrilateral

• Find the perimeter of the quadrilateral
