SAT ACT Prep How to find the area of a parallelogram using special right triangles

The video tutorial explains how to calculate the area of a parallelogram with given side lengths and angles. It covers the properties of parallelograms, including parallel sides and angle relationships. The instructor uses an analogy of measuring height to clarify the concept of base and height in geometry. The tutorial concludes with a step-by-step calculation of the area using trigonometric principles, specifically focusing on the 30-60-90 triangle relationships.

What is a key property of a parallelogram regarding its sides?

• Diagonals are equal.

• All angles are right angles.

• Opposite sides are parallel and equal.

• All sides are equal.

Why is it important to restate the problem question?

• To ensure you solve the correct problem.

• To make the problem more complex.

• To change the problem statement.

• To avoid solving the problem.

How should height be measured in a parallelogram?

• From one corner to the opposite corner.

• Using the length of any side.

• From the base to the top, perpendicular to the base.

• Along the slant of the side.

What type of triangle is used to find the height in this problem?

• Equilateral triangle

• Isosceles triangle

• 30-60-90 triangle

• 45-45-90 triangle

What is the relationship between the short leg and the hypotenuse in a 30-60-90 triangle?

• The hypotenuse is equal to the short leg.

• The hypotenuse is half the short leg.

• The hypotenuse is three times the short leg.

• The hypotenuse is twice the short leg.

How do you calculate the area of a parallelogram?

• Product of diagonals

• Sum of all sides

• Base times height

• Base times slant height

What is the final calculated area of the parallelogram in the problem?

• 36

• 12 times sqrt 3

• 18

• 18 times sqrt 3
