A protractor is a tool used to measure angles in degrees.

Front

What are special right triangles?

Back

Special right triangles are triangles with specific angle measures (30-60-90 and 45-45-90) that have known side ratios.

Front

How do you find the value of x using special right triangles?

Back

Use the known ratios of the sides of special right triangles to solve for x.

Front

What is the significance of the symbol for degrees (°)?

Back

The symbol for degrees (°) is used to indicate the measurement of angles.

Front

What does it mean to eliminate a wrong answer in multiple-choice questions?

Back

Eliminating a wrong answer involves identifying and removing options that are clearly incorrect to improve the chances of selecting the correct answer.

Front

What is the formula for the area of a triangle?

Back

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

Front

What is the Pythagorean theorem?

Back

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

Front

What is a fraction?

Back

A fraction represents a part of a whole and is expressed as a numerator over a denominator.
