Use special right triangles to determine the height to find the area of a parallelogram

The video tutorial covers the identification of geometric figures, specifically parallelograms, and explains how to calculate their area using the base and height. It introduces the properties of 30-60-90 triangles, emphasizing the relationships between the sides. The tutorial guides students through the process of finding the height using these properties and calculating the area of a parallelogram, ensuring they understand the importance of using correct units.

What is the formula for calculating the area of a parallelogram?

• Base times width

• Height times width

• Base times height

• Length times width

In a parallelogram, what is true about its opposite sides?

• They are equal in length

• They are perpendicular

• They are congruent

• They are parallel

What is the angle measure of the smallest angle in a 30-60-90 triangle?

• 45 degrees

• 90 degrees

• 60 degrees

• 30 degrees

In a 30-60-90 triangle, how is the hypotenuse related to the short leg?

• It is equal to the short leg

• It is twice the short leg

• It is half the short leg

• It is three times the short leg

How do you calculate the long leg in a 30-60-90 triangle?

• Divide the short leg by 2

• Multiply the short leg by sqrt 3

• Divide the short leg by sqrt 3

• Multiply the short leg by 2
