## How do I classify a triangle by its angles?

Classifying Triangles by Angles Triangles can also be classified by their angles. In an acute triangle all three angles are acute (less than 90 degrees). A right triangle contains one right angle and two acute angles. And an obtuse triangle contains one obtuse angle (greater than 90 degrees) and two acute angles.

What are the 3 angles of a triangle?

So, the three angles of a triangle are 30°, 60° and 90°.

What angle is a triangle?

180 degrees
Explanation: The angles of a triangle add together to 180 degrees. We already know that one of the angles is 90 degrees, so we can subtract 90 from 180: the other 2 angles have to add to 90 degrees.

### How do you find a hypotenuse?

The hypotenuse is termed as the longest side of a right-angled triangle. To find the longest side we use the hypotenuse formula that can be easily driven from the Pythagoras theorem, (Hypotenuse)2 = (Base)2 + (Altitude)2. Hypotenuse formula = √((base)2 + (height)2) (or) c = √(a2 + b2).

### Does a triangle have 3 equal sides?

An equilateral triangle has three equal sides and angles. It will always have angles of 60° in each corner.

Do angles of a triangle equal 180?

In a Euclidean space, the sum of angles of a triangle equals the straight angle (180 degrees, π radians, two right angles, or a half-turn). A triangle has three angles, one at each vertex, bounded by a pair of adjacent sides.

Why are the angles of a triangle 180?

A triangle’s angles add up to 180 degrees because one exterior angle is equal to the sum of the other two angles in the triangle. In other words, the other two angles in the triangle (the ones that add up to form the exterior angle) must combine with the third angle to make a 180 angle.

#### Do all triangles equal 180?

The angle sum of a triangle will always be equal to 180°. The angle sum of a quadrilateral is equal to 360°, and a triangle can be created by slicing a quadrilateral in half from corner to corner. Since a triangle is essentially half of a quadrilateral, its angle measures should be half as well. Half of 360° is 180°.

#### What kind of triangle is it with the following angles 60 60 and 60?

Isosceles Triangle
Isosceles Triangle degrees 60, 60, 60 | ClipArt ETC.

How to find the size of the third angle of a triangle?

Therefore, specifying two angles of a tringle allows you to calculate the third angle only. Given the sizes of 2 angles of a triangle you can calculate the size of the third angle. The total will equal 180° or π radians.

What is the ratio of a 30 60 90 triangle?

30°-60°-90° triangle: The 30°-60°-90° refers to the angle measurements in degrees of this type of special right triangle. In this type of right triangle, the sides corresponding to the angles 30°-60°-90° follow a ratio of 1:√ 3 :2.

## What is the value of the missing angle in the triangle?

As you know, the sum of angles in a triangle is equal to 180°. From this theorem we can find the missing angle: γ = 180°- α – β

## Why do we specify two angles of a tringle?

Specifying the three angles of a triangle does not uniquely identify one triangle. Therefore, specifying two angles of a tringle allows you to calculate the third angle only. Given the sizes of 2 angles of a triangle you can calculate the size of the third angle.
