Parallelograms and 30-60-90 Triangles

The video tutorial explains how to find the height of a parallelogram using two different methods. The first method involves using the area and base of the parallelogram to calculate the height. The second method uses the properties of a 30-60-90 right triangle to find the height when given the sides and an angle. The tutorial provides step-by-step instructions and examples to illustrate these concepts.

What is the formula for the area of a parallelogram?

• Side squared

• Base times height

• Length times width

• Base plus height
