SAT Practice #6 (Geometry)

Front

What is the Pythagorean Theorem?

Back

The Pythagorean Theorem states that in a right triangle, the square of the length of the hypotenuse (c) is equal to the sum of the squares of the lengths of the other two sides (a and b). Formula: a² + b² = c².

Front

Define a parallelogram.

Back

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

Front

What is the formula for the area of a triangle?

Back

The area of a triangle can be calculated using the formula: Area = 1/2 * base * height.

Front

Explain the concept of similar triangles.

Back

Similar triangles are triangles that have the same shape but may differ in size. Their corresponding angles are equal, and the lengths of corresponding sides are proportional.

Front

What is the difference between a radius and a diameter?

Back

The radius is the distance from the center of a circle to any point on its circumference, while the diameter is the distance across the circle through the center, equal to twice the radius.

Front

Define a circle's circumference.

Back

The circumference of a circle is the distance around it. It can be calculated using the formula: Circumference = 2 * π * radius.

Front

What is the formula for the volume of a cylinder?

Back

The volume of a cylinder can be calculated using the formula: Volume = π * radius² * height.

Front

Explain the concept of complementary angles.

Back

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

Front

What is the formula for the area of a rectangle?

Back

The area of a rectangle can be calculated using the formula: Area = length * width.

Front

Define an isosceles triangle.

Back

An isosceles triangle is a triangle that has at least two sides of equal length and the angles opposite those sides are equal.
