## How do you describe angles in a triangle?

The three interior angles in a triangle will always add up to 180°.

At each corner the exterior and interior angles are on a straight line, so at each corner these two angles add up to 180°.

An isosceles triangle has two lengths which are the same as each other, and two angles which are the same as each other..

## What are the 7 types of angles?

Types of Angles – Acute, Right, Obtuse, Straight and Reflex…Acute angle.Right angle.Obtuse angle.Straight angle.Reflex angle.

## What are the sides of an angle?

The sides of an angle refer to the two rays or line segments that form the angle. In the figure below, rays BA and BC are the sides of angle ABC. An angle is formed by rotating a ray around its endpoint.

## How do you notate an angle?

An angle in geometry is denoted by the angle symbol (∠) followed by three letters which represent points that form the angle. For example the figure below illustrates the angle formed between two lines.

## What is the sum of the interior angle of a triangle?

180°Triangle/Sum of interior angles

## What are 3 ways to name an angle?

The best way to describe an angle is with three points. One point on each ray and the vertex always in the middle. That angle could be NAMED in three ways: X, BXC, or CXB. Adjacent angles are two angles that have a common vertex, a common side, and no common interior points.

## What are the 4 ways to name an angle?

How to Name an Angle in Four WaysLabel an angle using the vertex and a point from each arm.Label an angle using only the vertex.Label an angle using numbers.

## What are the acceptable ways to name an angle?

(1) We can name angles by using THREE capital letters like: ABC or DEF. The middle letter is called the VERTEX of the angle. The above angles are read “angle ABC” and “angle DEF.” This leads us to the second way we can name angles. (2) We can name angles by using the vertex.

## What is the symbol for angle?

symbol ∠In geometry, an angle can be defined as the figure formed by two rays meeting at a common end point. An angle is represented by the symbol ∠.

## Which set of angles could be the interior angles of a triangle?

Answer: 19° ,70° and 91° only one represent the interior angle of triangle.

## What set of angle measures could be the interior angles of a triangle?

Explain why 1) 90°, 90°,90° 2)80°,80°,200° 3)40°,50°,60° 4)15°,30°,135° Sum of the interior angle of triangle is 180 so choice 4 is correct which is 15,30,135 add them and you will get 180.
