## Is sin and cos only for right triangles?

Though you can only use sin,cos,tan for only right triangles, You can always add an optional drawing to your non-right triangle (May it be acute or obtuse) to create right angled triangles.

**Can you use trig on right angles?**

A right angle has a value of 90 degrees (90∘ ). The relation between the sides and angles of a right triangle is the basis for trigonometry. The side opposite the right angle is called the hypotenuse (side c in the figure). The sides adjacent to the right angle are called legs (sides a and b ).

**Does sin only work on right triangles?**

Sine Rule. The Sine Rule can be used in any triangle (not just right-angled triangles) where a side and its opposite angle are known. You will only ever need two parts of the Sine Rule formula, not all three. Remember that each fraction in the Sine Rule formula should contain a side and its opposite angle.

### How do you do CAH in Sohcahtoa?

What Is SohCahToa?

- SOH: Sin(θ) = Opposite / Hypotenuse.
- CAH: Cos(θ) = Adjacent / Hypotenuse.
- TOA: Tan(θ) = Opposite / Adjacent.

**How do you use CAH?**

The hypotenuse is always opposite the right angle. The sine of an angle is equal to the side opposite the angle divided by the hypotenuse….Sohcahtoa Calculator.

Soh… | Sine = Opposite / Hypotenuse |
---|---|

…cah… | Cosine = Adjacent / Hypotenuse |

…toa | Tangent = Opposite / Adjacent |

**Can you use Sohcahtoa on a non right triangle?**

For right-angled triangles, we have Pythagoras’ Theorem and SOHCAHTOA. However, these methods do not work for non-right angled triangles.

## How do you calculate CAH?

CAH: Cos(θ) = Adjacent / Hypotenuse. TOA: Tan(θ) = Opposite / Adjacent.

**How to use Sohcahtoa to find the unknown angles?**

How to use SOHCAHTOA to find the unknown angles of right angled triangles 1 Label the sides of the right-angled triangle that we have information about.. 2 Choose the trig ratio we need.. 3 Substitute the values from the triangle into the function.. Using inverse trig functions, work out the missing angle θ. More

**What are the Sohcahtoa triangles?**

We can abbreviate these to the SOHCAHTOA triangles: What is SOHCAHTOA? The hypotenuse is the longest side of the triangle. It is opposite the right angle. The opposite side is the side that is opposite the angle. The adjacent side is the side that is adjacent (next to) the angle.

### What is Sohcahtoa?

What is SOHCAHTOA? SOHCAHTOA is a mnemonic that gives us an easy way to remember the three main trigonometric ratios. They are sine (sin), cosine (cos) and tangent (tan). We can use these to work out missing sides and angles in right-angled triangles.

**What is Sohcahtoa mnemonic?**

SOHCAHTOA is a mnemonic that gives us an easy way to remember the three main trigonometric ratios. They are sine (sin), cosine (cos) and tangent (tan). We can use these to work out missing sides and angles in right-angled triangles.
