What is the formula to find the missing angle in a right triangle?

Back

The missing angle can be found using the formula: x = 90° - (other angle).

What is the definition of altitude in a triangle?

Back

The altitude of a triangle is the perpendicular segment from a vertex to the line containing the opposite side.

How do you calculate the length of a side in a right triangle using the Pythagorean theorem?

Back

The Pythagorean theorem states that a² + b² = c², where c is the hypotenuse.

What is the hypotenuse in a right triangle?

Back

The hypotenuse is the longest side of a right triangle, opposite the right angle.

What is the definition of a leg in a right triangle?

Back

A leg is one of the two shorter sides of a right triangle that form the right angle.

Front

If one leg of a right triangle is 16.0 and the other leg is 4.1, how do you find the hypotenuse?

Back

Use the Pythagorean theorem: c = √(16.0² + 4.1²) = 16.3.

Front

What is the approximate value of the hypotenuse if the legs are 16.0 and 4.1?

Back

The hypotenuse is approximately 16.3.

Front

How do you round a number to the nearest degree?

Back

Look at the decimal: if it's 0.5 or higher, round up; if it's less than 0.5, round down.

Front

What is the approximate value of angle x if it is calculated to be 52.3 degrees?

Back

Angle x is approximately 52 degrees when rounded to the nearest degree.

Front

What is the relationship between the angles in a right triangle?

Back

The sum of the angles in a right triangle is always 180 degrees, with one angle being 90 degrees.
