When to lines intersect they create four

**angles**. Each**angle**is opposite to another and form a pair of what are called opposite**angles**.**Angles**a and c are opposite**angles**.**Angles**b and d are opposite**angles**. Opposite**angles**are equal.

Correspondingly, what is a property of a angle?

**Angle** Definition and **Properties** of **Angles**. An **angle** is a shape formed by two rays that have a common endpoint. In Trigonometry an **angle** is in standard position if one ray is on the positive x axis (called the initial side) and the vertex is at the origin. m∠B=45° means the measure of **angle** B is 45 degrees.

**angles**are equal. The vertically opposite

**angles**are equal. The alternate interior

**angles**are equal. The alternate exterior

**angles**are equal.

Types of Angles | Angles |
---|---|

Vertically opposite Angles | (∠1, ∠3), (∠2, ∠4), (∠5, ∠7), (∠6, ∠8) |

Corresponding Angles | (∠1, ∠5), (∠2, ∠6), (∠3, ∠7), (∠4, ∠8) |

Similarly, it is asked, how do you find the angle properties?

**Angle Properties**

- Angles on a Straight Line Add Up to 180° If you have a straight line and one or more lines emerging from this line from a point at an angle, the angle(s) will add up to 180°.
- Vertically Opposite Angles are Equal.
- Alternate Angles are Equal.
- Co-interior angles add up to 180°
- Corresponding Angle Property.

The sum of all internal **angles** of a **triangle** is always equal to 180^{0}^{.} This is called the **angle** sum **property of a triangle**. The sum of the length of any two sides of a **triangle** is greater than the length of the third side. The side opposite to the largest **angle** of a **triangle** is the largest side.
