What is the difference between a scalene and acute triangle

The angles containing the base as a side are called the "base angles". Note: The base angles in an isosceles triangle are of the same measure. An equilateral triangle has three congruent sides.

An equilateral triangle may also be called a "regular" triangle. A "regular" polygon has all equal sides and all equal angles. Note: It is possible for an acute triangle to also be scalene, isosceles, or equilateral. A right triangle has one right angle. A "box" is used to indicate the location of the right angle. The longest side of the right triangle across from the "box" is called the "hypotenuse".

In an acute triangle, all angles are less than right angles? An acute triangle may be equilateral, isosceles, or scalene. Updated February 11, Infoplease Staff. Numbers and Formulas. See also:.
