An obtuse triangle is any triangle that has an obtuse angle. A scalene triangle is one which have all three sides of a triangle of different lengths and all three angles of different measures.

There is no line of symmetry. In this triangle, angle E will be the greatest angle as it is opposite to the greatest side GO and angle O will be the smallest angle as it is opposite to the smallest side GE. A scalene triangle can be acute-angled or obtuse-angled or right-angled.

Note: It is possible for a right triangle to also be scalene or isosceles. An obtuse triangle has one angle measuring more than 90º but less than 180º (an obtuse angle). It is not possible to draw a triangle with more than one obtuse angle. Note: It is possible for an obtuse triangle to also be scalene or isosceles.

An isosceles triangle is a triangle in which exactly two sides are the same length. An obtuse triangle is a triangle with one angle that is greater than 90 degrees. A scalene triangle is a triangle in which all three sides are different lengths. A triangle is a polygon with three sides and three angles.

For a triangle to be considered scalene, it needs to have: three different angle measures that add up to 180 degrees. three sides of different lengths, or noncongruent sides.

Comparison-Scalene, Isosceles and Equilateral

A triangle with all sides of different lengths. So no sides are equal and no angles are equal. …

Since all three angles less than 90° and all three angles are different measurements. So, It is an acute scalene triangle.
