**triangle**has three

**angles**. The sum of the measures of the

**angles**is always 180° in a

**triangle**. We have different types of

**triangles**. A

**triangle**is classified by its

**angles**and by the number of congruent sides.

Herein, what angle does a triangle have?

The right **triangle has** one 90 degree **angle** and two acute (< 90 degree) **angles**. Since the sum of the **angles** of a **triangle** is always 180 degrees The two sides of the **triangle** that **are** by the right **angle are** called the legs and the side opposite of the right **angle** is called the hypotenuse.

Likewise, can a triangle have a 0 degree angle? The key reason that **triangles** cannot **have angles** which measure **0** ∘ **0** ^ circ **0**∘ is that such a figure would necessarily be 3 points on a straight line, and such a figure is not a **triangle**. Recall that the **triangle** inequality states that in a **triangle**, we **have** a + b > c a + b > c a+b>c.

In this regard, are all angles of a triangle equal?

In a Euclidean space, the sum of measures of these three **angles** of any **triangle** is invariably **equal** to the straight **angle**, also expressed as 180 °, π radians, two right **angles**, or a half-turn. It was unknown for a long time whether other geometries exist, where this sum is different.

How do I find the degree of an angle in a triangle?

Remember -- the sum of the **degree** measures of **angles** in any **triangle** equals 180 **degrees**. Below is a picture of **triangle** ABC, where **angle** A = 60 **degrees**, **angle** B = 50 **degrees** and **angle** C = 70 **degrees**. If we add all three **angles** in any **triangle** we get 180 **degrees**.
