Int 2: Unit 4 Review

Front

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

Back

Area = 1/2 * base * height.

Front

Define the sine function in a right triangle.

Back

Sine (sin) is the ratio of the length of the opposite side to the length of the hypotenuse.

Front

What is the formula for the area of a rectangle?

Back

Area = length * width.

Front

How do you find the length of a side in a right triangle using the Pythagorean theorem?

Back

a² + b² = c², where c is the hypotenuse.

Front

What is the ratio for Cosine in a right triangle?

Back

Cosine (cos) is the ratio of the length of the adjacent side to the length of the hypotenuse.

Front

What is the ratio for Tangent in a right triangle?

Back

Tangent (tan) is the ratio of the length of the opposite side to the length of the adjacent side.

Front

How do you calculate the area of a circle?

Back

Area = π * radius².

Front

What is the relationship between the angles in a triangle?

Back

The sum of the interior angles in a triangle is always 180 degrees.

Front

What is the formula for the perimeter of a rectangle?

Back

Perimeter = 2 * (length + width).

Front

How do you find the height of a triangle if you know the area and base?

Back

Height = (2 * Area) / base.
