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

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

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

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

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

*Note:*The angles in an equilateral triangle are also of equal procedures (60º each).

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

*Note:*the is possible for one acute triangle to also be scalene, isosceles, or equilateral.

A right triangle has one appropriate angle. (A right angle measures exactly 90º.) A "box" is provided to suggest the place of the appropriate angle. The longest side of the best triangle (across native the "box") is called the "hypotenuse". The staying two sides are described as "legs", i m sorry may, or may not, it is in of equal length.

*Note:*the is possible for a best triangle to likewise be scalene or isosceles.

An obtuse triangle has actually one edge measuring much more than 90º yet less than 180º (an obtuse angle). The is not feasible to draw a triangle with more than one obtuse angle.

*Note:*It is possible for an obtuse triangle to additionally 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.
