** species of triangle ** bsci-ch.org Topical rundown | Geometry synopsis | MathBits" Teacher resources **Terms that Use call Person:** Donna Roberts

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

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

An isosceles triangle has actually two congruent sides. The political parties that space the same lengths are called the "legs". The various other side is called the "base". The angle between the legs is dubbed the "vertex angle". The angles containing the base together a next are called the "base angles".

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

An equilateral triangle has three congruent sides. An equilateral triangle may additionally be referred to as a "regular" triangle. (A "regular" polygon has all equal sides and also all equal angles.)

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

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

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

A right triangle has actually one best angle. (A ideal angle measures precisely 90º.) A "box" is supplied to show the ar of the best angle. The longest side of the ideal triangle (across native the "box") is dubbed the "hypotenuse". The continuing to be two sides are described as "legs", i m sorry may, or might not, be of same length.

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

An obtuse triangle has one edge measuring an ext than 90º however less than 180º (an obtuse angle). It is not possible to draw a triangle with more than one obtuse angle.

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

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

*Note:*All equiangular triangles are also equilateral.
