Front

What is a right triangle?

Back

A right triangle is a triangle that has one angle measuring 90 degrees.

Front

How do you calculate the area of a triangle?

Back

Area = 1/2 * base * height.

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): a² + b² = c².

Front

What is the distance formula?

Back

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

Front

What are parallel lines?

Back

Parallel lines are lines in a plane that never meet; they are always the same distance apart.

Front

What are intersecting lines?

Back

Intersecting lines are lines that cross each other at one point.

Front

What are perpendicular lines?

Back

Perpendicular lines are lines that intersect at a right angle (90 degrees).

Front

How do you find the width of a rectangle given the diagonal and height?

Back

Use the Pythagorean theorem: width = √(diagonal² - height²).

Front

What is the formula for the area of a rectangle?

Back

Area = length * width.

Front

What is the formula for the area of a circle?

Back

Area = π * radius².
