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.

How do you find the length of a missing side in a right triangle?

Back

Use the Pythagorean Theorem: a² + b² = c², where c is the hypotenuse and a and b are the other two sides.

What is the sine function in trigonometry?

Back

The sine function (sin) is defined as the ratio of the length of the opposite side to the length of the hypotenuse in a right triangle.

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

Back

In a right triangle, the larger the angle, the longer the opposite side. The sum of the angles in any triangle is always 180 degrees.

How do you calculate the angle of elevation?

Back

The angle of elevation is calculated using the inverse tangent function (tan⁻¹) of the ratio of the opposite side to the adjacent side.

What is the hypotenuse in a right triangle?

Back

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