## What is the ratio of an angle?

The sine of an angle is the trigonometric ratio of the opposite side to the hypotenuse of a right triangle containing that angle. Cosine: The cosine of an angle is the trigonometric ratio of the adjacent side to the hypotenuse of a right triangle containing that angle.

### What is the ratio of sine θ?

Trigonometric Ratios | |
---|---|

Sin θ | Opposite Side to θ/Hypotenuse |

Cot θ | Adjacent Side/Opposite Side & 1/tan θ |

Sec θ | Hypotenuse/Adjacent Side & 1/cos θ |

Cosec θ | Hypotenuse/Opposite Side & 1/sin θ |

**What are the 3 trigonometric ratios?**

The three trig ratios in question are sine (sin), cosine (cos) and tangent (tan).

**What are six trigonometric ratios?**

There are six functions of an angle commonly used in trigonometry. Their names and abbreviations are sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant (csc).

## What is Hyp over Opp?

Always, always, the sine of an angle is equal to the opposite side divided by the hypotenuse (opp/hyp in the diagram). The cosine is equal to the adjacent side divided by the hypotenuse (adj/hyp).

### What are the 6 trigonometric ratios?

**What are the names of the angles in math?**

1 Names of Angles. Also: Acute, Obtuse and Reflex are in alphabetical order. Also: the letter “A” has an acute angle. 2 Be Careful What You Measure. So when naming the angles make sure that you know which angle is being asked for ! 3 Positive and Negative Angles. The angle is the amount of turn between each arm.

**What are the trigonometric ratios of standard angles?**

It consists of trigonometric ratios – sine, cosine, tangent, cosecant, secant, cotangent. These ratios can be written in short as sin, cos, tan, cosec, sec and cot. The values of trigonometric ratios of standard angles are essential to solve the trigonometry problems.

## Are the ratios for acute angles the same for every triangle?

So, all the ratios for any of the acute angles (either ∠ A or ∠ C) will be the same for every right triangle. This means that the ratios are independent of lengths of sides of the triangle.

### What are the degrees of right angle?

Acute Angle: is less than 90° Right Angle: is 90° exactly: Obtuse Angle: is greater than 90° but less than 180° Straight Angle: is 180° exactly: Reflex Angle: is greater than 180° Full Rotation: is 360° exactly
