What is the distance formula in a coordinate plane?

Back

The distance between two points (x1, y1) and (x2, y2) is given by the formula: d = √((x2 - x1)² + (y2 - y1)²).

Front

How do you find the midpoint of a line segment?

Back

The midpoint M of a line segment with endpoints (x1, y1) and (x2, y2) is given by: M = ((x1 + x2)/2, (y1 + y2)/2).

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.

Front

What is the definition of complementary angles?

Back

Complementary angles are two angles whose sum is 90 degrees.

Front

What is the definition of supplementary angles?

Back

Supplementary angles are two angles whose sum is 180 degrees.

Front

How do you calculate the angle of elevation?

Back

The angle of elevation is the angle between the horizontal line and the line of sight to an object above the horizontal.

Front

What is the formula for the area of a triangle?

Back

The area A of a triangle is given by: A = (base * height) / 2.

Front

What is the Pythagorean theorem?

Back

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): c² = a² + b².

Front

How do you find the missing angle in a triangle?

Back

To find the missing angle in a triangle, subtract the sum of the known angles from 180 degrees.

Front

What is the definition of a line segment?

Back

A line segment is a part of a line that is bounded by two distinct endpoints.
