# ANGLES OF A TRIANGLE

Angles of a triangle
lbartmanImage: lbartmanDefinition of angles inside a triangle: 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.

Triangle - Wikipedia
By internal angles. A triangle with an interior angle of 180° (and collinear vertices) is degenerate. A right degenerate triangle has collinear vertices, two of which are coincident. A triangle that has two angles with the same measure also has two sides with the same length, and therefore it is an isosceles triangle.

It is not possible for a triangle to have more than one vertex with internal angle greater than or equal to 90°, or it would no longer be a triangle. 2. 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. Another way to calculate the exterior angle of a triangle is to subtract the angle of the vertex of interest from 180°. 3. The sum of the lengths of any two sides of a..See more on calculator

Angles Can Be AddedFinding A Missing AngleEquilateral TrianglesA Ratio of AnglesJust like regular numbers, angles can be added to obtain a sum, perhaps for the purpose of determining the measure of an unknown angle. Sometimes we can determine a missing angle because we know that the sum must be a certain value. 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.

owlcation›STEM›MathFeb 16, 2016By definition, a triangle is a polygon with three sides. Polygons are plane (flat, two-dimensional) shapes with several straight sides. Other examples include squares, triangles, hexagons, and pentagons. The name originates from the Greek polús meaning "many" and Reviews: 52Author: Eugene Brennan

Triangles - Equilateral, Isosceles and Scalene
Imagine you "doubled" the triangle (flip it around one of the upper edges) to make a square-like shape (a parallelogram ) which can be changed to a simple rectangle: THEN the whole area is bh, which is for both triangles, so just one is ½ × bh.
