What is the opposite adjacent and hypotenuse?
In a right triangle, the hypotenuse is the longest side, an “opposite” side is the one across from a given angle, and an “adjacent” side is next to a given angle. We use special words to describe the sides of right triangles.
What does SOH CAH TOA stand for?
“SOHCAHTOA” is a helpful mnemonic for remembering the definitions of the trigonometric functions sine, cosine, and tangent i.e., sine equals opposite over hypotenuse, cosine equals adjacent over hypotenuse, and tangent equals opposite over adjacent, (1) (2) (3)
How does SOH CAH TOA work?
The sine of an angle is equal to the side opposite the angle divided by the hypotenuse. The cosine of an angle is equal to the side adjacent to the angle divided by the hypotenuse….Sohcahtoa Calculator.

What is the opposite of adjacent?
A convenient mnemonic for remembering the definition of the sine, cosine, and tangent is SOHCAHTOA (sine equals opposite over hypotenuse, cosine equals adjacent over hypotenuse, tangent equals opposite over adjacent). These geometrical objects are then called a tangent line or tangent plane, respectively.
What is the ratio of the opposite to the hypotenuse?
Let us start with some definitions. We will call the ratio of the opposite side of a right triangle to the hypotenuse the sine and give it the symbol sin. The ratio of the adjacent side of a right triangle to the hypotenuse is called the cosine and given the symbol cos.
Does Sohcahtoa work on non right triangles?
For right-angled triangles, we have Pythagoras’ Theorem and SOHCAHTOA. However, these methods do not work for non-right angled triangles.
How do you find the opposite of a hypotenuse?
The Sine Function: Opposite over Hypotenuse
- Find the length of the side opposite alpha. Use the Pythagorean theorem, a2 + b2 = c2, letting a be 8 and c be 10. When you input the numbers and solve for b, you get. So, the opposite side is 6 inches long.
- Use the ratio for sine, opposite over hypotenuse.
Why is sine opposite over hypotenuse?
The sine is always the measure of the opposite side divided by the measure of the hypotenuse. Because the hypotenuse is always the longest side, the number on the bottom of the ratio will always be larger than that on the top. So, the opposite side is 6 inches long. Use the ratio for sine, opposite over hypotenuse.
