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

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

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

*Note:*The base angles in an isosceles triangle space of the exact same measure.

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

*Note:*The angles in an it is provided triangle are likewise of equal actions (60º each).

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

*Note:*it is possible for an acute triangle to likewise be scalene, isosceles, or equilateral.

A ideal triangle has actually one ideal angle. (A right angle measures precisely 90º.) A "box" is supplied to show the location of the ideal angle. The longest next of the best triangle (across indigenous the "box") is dubbed the "hypotenuse". The staying two sides are referred to as "legs", i m sorry may, or might not, it is in of equal length.

*Note:*it is possible for a appropriate triangle to also be scalene or isosceles.

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

*Note:*It is feasible for an obtuse triangle to also be scalene or isosceles.

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

*Note:*All equiangular triangle are also equilateral.
