What is the Sine Ratio in a right triangle?

Back

The Sine Ratio is defined as the ratio of the length of the opposite side to the length of the hypotenuse. Formula: Sine(θ) = Opposite/Hypotenuse.

What is the Tangent Ratio in a right triangle?

Back

The Tangent Ratio is defined as the ratio of the length of the opposite side to the length of the adjacent side. Formula: Tangent(θ) = Opposite/Adjacent.

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 the hypotenuse using the Pythagorean Theorem?

Back

To find the hypotenuse (c), use the formula: c = √(a² + b²), where a and b are the lengths of the other two sides.
