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

*Note:*The angles in a scalene triangle are additionally of different measures.

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

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

An equilateral triangle has actually three congruent sides. An equilateral triangle may likewise be dubbed a "regular" triangle. (A "regular" polygon has actually all equal sides and all equal angles.)

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

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

*Note:*that is feasible for an acute triangle to also be scalene, isosceles, or equilateral.

A ideal triangle has actually one appropriate angle. (A right angle measures specifically 90º.) A "box" is provided to suggest the location of the ideal angle. The longest next of the ideal triangle (across indigenous the "box") is referred to as the "hypotenuse". The continuing to be two political parties are referred to as "legs", i m sorry may, or might not, be of same length.

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

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

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

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

*Note:*All equiangular triangles are additionally equilateral.
