A scalene triangle has no equal sides. There is no word for a triangle with three different angle sizes. The words describing angle sizes — right, obtuse and acute — reference the degrees of the angle, not their relation...

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.

A shape that has three unequal sides is a scalene triangle. A shape that has four unequal sides is a quadrilateral. A shape that has more than four unequal sides is an irregular polygon.

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. ...

Four different methods for determining triangle congruency by examining sets of sides and angles exist: SSS (side, side, side), SAS (side, angle, side), ASA (angle, side, angle) and AAS (angle, angle, side). The hypotenu...

A scalene triangle has no parallel sides and no equal angles. The three noncongruent sides of a scalene triangle are of different lengths, and the measurements of the three unequal angles inside the triangle, like those ...
