## What are the angles of a triangle?

The interior angles of a triangle always add up to 180° while the exterior angles of a triangle are equal to the sum of the two interior angles that are not adjacent to it.

### What is a triangle with 2 angles?

Isosceles Triangle
Isosceles Triangle. . This property is equivalent to two angles of the triangle being equal.

#### What are the two sides of a triangle called?

The sides of a triangle are given special names in the case of a right triangle, with the side opposite the right angle being termed the hypotenuse and the other two sides being known as the legs.

How do you find the angle of a triangle with two angles?

The key to finding the missing angle measure of a triangle is to remember that the sum of the interior angles of any triangle is always 180°. If you know 2 angles then you can subtract their sum from 180° to find the measure of the 3rd angle.

How do you find two angles of a triangle?

Answer: If you know two angles, then you can work out the third since all the angles sum to 180 degrees. If the sides are a, b and the hypotenuse is c (opposite angle A), and the angles are A, B and C, then Sin A = a/c, so a = cSin A. Also Cos A = b/c, so b = cCos A.

## How do you find an angle of a triangle with two angles?

### What are sides angles?

The sides of an angle refer to the two rays or line segments that form the angle. An angle is formed by rotating a ray around its endpoint. The initial side of an angle is the beginning position of the ray, and the terminal side is the position of the ray after it is rotated.

#### How do you calculate the side of a triangle?

According to the Law of Sines, the ratio of the sines of each angle divided by the length of the opposite side are all equal. This helps you to find the sides of the triangle. Add the two angles together and subtract the sum from 180 degrees to find the third angle.

How do you solve the triangle?

To solve an SAS triangle use The Law of Cosines to calculate the unknown side, then use The Law of Sines to find the smaller of the other two angles, and then use the three angles add to 180° to find the last angle.

How do you calculate triangles?

There are multiple rules to calculate a triangle’s area: SSS (side-side-side), SAS (two sides and the included angle), SSA (two sides and a non-included angle), ASA (two angles and the included side). For right-angled triangles you can calculate the area by knowing the hypothenuse and the height towards it.

The triangle is a two-dimensional shape with three inside angles. These inside angles are said to be interior angles of the triangle and it will sum up to 180 degrees. These inside angles are classified into three types: Angle 1+angle 2+ angles 3= 180 degrees.
