Calculate the sum of the squares of the two shorter sides. If this is less than the square of the remaining, third, side then the triangle is obtuse.
There are three possibilities - let the three sides of the triangle be A, B and C with C the longest side (that is C ≥ A and C ≥ B). Then, if:
- A2 + B2 > C2 the triangle is acute
- A2 + B2 = C2 the triangle is right angled
- A2 + B2 < C2 the triangle is obtuse

What are the lengths of the sides of an obtuse triangle?
The 3 sides have different lengths
Are the medians of an obtuse angle the same length?
In an obtuse triangle, the medians do not have to be the same length. The lengths of the medians depend on the lengths of the sides of the triangle, which can vary regardless of whether the triangle is acute, right, or obtuse. Therefore, unless the triangle is isosceles (where two sides are equal), the medians will generally be different lengths.
What is a shape with no congruent sides and one of it's angles is obtuse?
An obtuse scalene triangle would fit the given description
Can you draw a scalene obtuse triangle?
Yes. Scalene simply means that a triangle's sides are all different lengths. Obtuse means that a triangle has an obtuse angle. Therefore, you can have an obtuse scalene triangle.
What is the difference between an scalene right triangle and a scalene obtuse triangle?
A scalene triangle is a triangle in which all three sides have different lengths. The difference between a scalene right triangle and a scalene obtuse triangle is that in the first one, we can find the measure length of the third side when we know the lengths of the two other sides, and in the second one we cannot.

What are the angle measurements of an obtuse scalene triangle?
i depends of the lengths of the sides

How can you tell if the given lengths can be the sides of a triangle?
you can fine the perimeter
What is triangle is an obtuse triangle?
An obtuse triangle is a type of triangle that has no congruent sides. Basically none of its sides are the same size.
Does a obtuse triangle have at least 2 equal sides?
obtuse triangle
Are scalene triangles all obtuse?
No, a scalene triangle is simply a triangle where all angles are not equal and all side lengths are not equal, therefore they can or cannot be obtuse.
How do you find out if a triangle is acute obtuse or a right triangle by the side lengths?
To determine if a triangle is acute, obtuse, or right based on its side lengths, you can use the Pythagorean theorem. For a triangle with sides (a), (b), and (c) (where (c) is the longest side), if (a^2 + b^2 = c^2), the triangle is right. If (a^2 + b^2 > c^2), it is acute, and if (a^2 + b^2 < c^2), it is obtuse.
Does an obtuse triangle always have 3 congruent sides?
An obtuse triangle does not always have three congruent sides. An obtuse triangle can be any form that always has three angles.
