text: An isosceles triangle also has two angles of the same measure, namely the angles opposite to the two sides of the same length; this fact is the content of the isosceles triangle theorem, which was known by Euclid.
text: Three positive angles α, β, and γ, each of them less than 180°, are the angles of a triangle if and only if any one of the following conditions holds:
text: Angle C is always 90 degrees; angle 3 is either angle B or angle A, whichever is NOT entered.
text: The angle included by the legs is called the vertex angle and the angles that have the base as one of their sides are called the base angles.
text: Angle C is always 90 degrees; angle 3 is either angle B or angle A, whichever is NOT entered.
text: The interior angle whose vertex is the opposite corner can be called the angle opposite to the side.
