A scalene triangle has three political parties of various lengths. No congruent sides.

*Note:*The angle in a scalene triangle are likewise of various measures.

An isosceles triangle has two congruent sides. The sides that room the same lengths are dubbed the "legs". The various other side is dubbed the "base". The angle between the legs is referred to as the "vertex angle". The angles containing the base together a next are referred to as the "base angles".

*Note:*The base angle in one isosceles triangle room of the exact same measure.

An equilateral triangle has actually three congruent sides. An it is provided triangle may additionally be called a "regular" triangle. (A "regular" polygon has all same sides and also all equal angles.)

*Note:*The angle in an it is intended triangle are also of equal procedures (60º each).

An acute triangle has actually all angles measuring less than 90º.

*Note:*it is feasible for one acute triangle to additionally be scalene, isosceles, or equilateral.

A right triangle has one right angle. (A ideal angle measures specifically 90º.) A "box" is supplied to suggest the ar of the ideal angle. The longest side of the ideal triangle (across native the "box") is referred to as the "hypotenuse". The continuing to be two sides are referred to as "legs", i m sorry may, or may not, it is in of equal length.

*Note:*that is possible for a right triangle to also be scalene or isosceles.

An obtuse triangle has one angle measuring more than 90º yet less than 180º (an obtuse angle). It is not possible to attract a triangle with much more than one obtuse angle.

*Note:*It is possible for one obtuse triangle to additionally be scalene or isosceles.

An equiangular triangle has three congruent angles. Each angle has a measure of 60º.

*Note:*All equiangular triangle are also equilateral.
