Geometry Final Exam Review

Front

What is the measure of an angle in a triangle if the other two angles are 65 degrees and 115 degrees?

Back

The measure of the angle is 180 - (65 + 115) = 0 degrees.

Front

What is the formula for the area of a triangle?

Back

Area = 1/2 * base * height.

Front

What is the height of a triangle with a base of 10 cm and an area of 35 cm²?

Back

Height = (2 * Area) / base = (2 * 35) / 10 = 7 cm.

Front

What is a midsegment in a triangle?

Back

A midsegment is a line segment connecting the midpoints of two sides of a triangle.

Front

If the midsegment of a triangle is 15 cm, what is the length of the third side?

Back

The length of the third side is twice the length of the midsegment, so it is 30 cm.

Front

What is the formula for the area of a rectangle?

Back

Area = length * width.

Front

If a rectangle has a length of 10 in and a width of 5 in, what is its area?

Back

Area = 10 * 5 = 50 in².

Front

What is the Pythagorean theorem?

Back

In a right triangle, a² + b² = c², where c is the hypotenuse.

Front

If one leg of a right triangle is 3 cm and the other leg is 4 cm, what is the length of the hypotenuse?

Back

Hypotenuse = √(3² + 4²) = √(9 + 16) = √25 = 5 cm.

Front

What is the sum of the interior angles of a triangle?

Back

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