Part 3 Final Review

Front

What is a parallelogram?

Back

A parallelogram is a four-sided figure (quadrilateral) with opposite sides that are both equal in length and parallel.

Front

How do you determine if a quadrilateral is a parallelogram using side lengths?

Back

If both pairs of opposite sides are equal in length, the quadrilateral is a parallelogram.

Front

What are complementary angles?

Back

Complementary angles are two angles whose measures add up to 90 degrees.

Front

What are supplementary angles?

Back

Supplementary angles are two angles whose measures add up to 180 degrees.

Front

If angle 1 = 27°, what is the measure of angle 2 if they are supplementary?

Back

Angle 2 = 180° - 27° = 153°.

Front

What is the sine function in trigonometry?

Back

The sine function relates the angle of a right triangle to the ratio of the length of the opposite side to the length of the hypotenuse.

Front

What is the cosine function in trigonometry?

Back

The cosine function relates the angle of a right triangle to the ratio of the length of the adjacent side to the length of the hypotenuse.

Front

What is the tangent function in trigonometry?

Back

The tangent function relates the angle of a right triangle to the ratio of the length of the opposite side to the length of the adjacent side.

Front

How do you find the value of 'a' in a triangle?

Back

Use the appropriate trigonometric function based on the known angles and sides.

Front

What is the formula for the area of a parallelogram?

Back

Area = base × height.
