Best Answer

If you know the lengths of the sides, you can use the cosine rule. If you have information about other aspects of the triangle, then other formulae will apply.

No, An equilateral triangle has 3 congruent angles, an isosceles triangle has 2 congruent angles, a scalene triangle has no congruent angles.

no angles in a scalene triangle should be equal. its called a scalene triangle because none of the angles or sides ar similar or congruent.

A triangle with no equal sides or angles will always be classified as 'scalene'.

scalene triangle dose not have any equal sides or angles =)

A scalene triangle is a triangle in which all three sides and all three angles are different. Therefore two angles of a scalene triangle are NEVER congruent.

no because if an scalene triangle had 2 congruent angles it wouldn't be a scalene it would be a isosceles triangle because an isosceles triangle is the only triangle with 2 congruent angles
