zero
Equilateral triangle = All sides congruent Scalene triangle = No sides congruent Isosceles triangle = At LEAST two sides congruent Right triangle = Triangle with one right angle Obtuse triangle = Triangle with ONE obtuse angle Acute triangle = Triangle with ALL acute angles
A scalene triangle can have an obtuse angle and two different acute angles.
Obtuse Triangle
An obtuse triangle does not always have three congruent sides. An obtuse triangle can be any form that always has three angles.
It is a scalene triangle
n obtuse angle
An isosceles obtuse triangle is a triangle with 1 obtuse angle and only 2 congruent sides.
A triangle with two congruent sides is isosceles. A triangle with an angle of 104 degrees is obtuse. So you would have an obtuse isosceles triangle.
An obtuse triangle is a type of triangle that has no congruent sides. Basically none of its sides are the same size.

Classification of triangles according to sides: -Scalene Triangle - a triangle with no 2 congruent sides. -Isosceles Triangle - a triangle with at least 2 congruent sides. -Equilateral Triangle - a triangle with 3 congruent sides. Classification of triangles according to angles: -acute triangle - a triangle with 3 acute angles. -right triangle - a triangle with one right angle. -equiangular triangle - a triangle with 3 congruent angles. -obtuse triangle - a triangle with one obtuse angle.
right triangle forms a 90 degree angle scalene triangle has no congruent sides isosceles triangle has at least 2 congruent sides equilateral triangle has 3 congruent sides acute triangle all angles measure less than 90 degrees and the obtuse triangle contains 1 obtuse angles.
