No matter what type of triangle is in question, there are always three angles in a triangle. The angle sizes vary on the type of triangle, but there are always three that add up to 180 degrees.

A triangle can have two acute angles. Some examples of triangle types that have two acute angles are a right triangle and an isosceles right triangle.

The angle bisector theorem states that a line bisecting an angle in a triangle divides the side opposite the angle into two line segments that have lengths proportional to the lengths of the other sides. An angle bisecto...

Every triangle has three angles, and the sum of those angles is always 180 degrees. This is true whether the triangle is an equilateral, isosceles, scalene or right triangle.

An isosceles triangle is a specific type of triangle where only two of the side lengths and two of the internal angles are equal. There are also other types of triangles like equilateral triangles and scalene triangles.

The three interior angles of a triangle always add up to 180 degrees, which is one of the identifying characteristics of a triangle. Each shape has properties that are unique to that specific figure. Other identifying pr...

Three laws can be used to find the sides and angles of almost any triangle: the Law of Angles, the Law of Sines, and the Law of Cosines. The Law of Angles means that all three angles of a triangle add up to 180 degrees. ...
