# What defines an obtuse triangle?

## What defines an obtuse triangle?

An obtuse triangle is a triangle in which one of the angles is an obtuse angle. (Obviously, only a single angle in a triangle can be obtuse or it wouldn’t be a triangle.) A triangle must be either obtuse, acute, or right.

## What is the definition of scalene triangle?

Definition of scalene of a triangle. : having the three sides of unequal length — see triangle illustration.

Are all obtuse triangles scalene?

Types of Triangle by Angle A right triangle may be isosceles or scalene. In an obtuse triangle, one angle is greater than a right angle—it is more than 90 degrees. An obtuse triangle may be isosceles or scalene.

Is an obtuse triangle isosceles?

Answer and Explanation: Yes, an obtuse triangle can be isosceles. The definitions of each of these types of triangles are as follows: An obtuse triangle is a triangle with…

### What does a obtuse scalene triangle look like?

An obtuse triangle is any triangle that has an obtuse angle. An obtuse angle is one that measures greater than 90 degrees. An acute angle is one that measures less than 90 degrees. A scalene triangle is one which have all three sides of a triangle of different lengths and all three angles of different measures.

### Why is a triangle called scalene?

Since all the three sides are unequal, this means all the three angles are also of different measures. It is one of the three types of triangles which is distinguished based on the properties of its sides. Hence, when none of the sides of a triangle are equal, we call it a scalene triangle.

What are scalene triangles?

A scalene triangle is a triangle in which all three sides are in different lengths, and all three angles are of different measures. However, the sum of all the interior angles is always equal to 180 degrees. Thus, it meets the angle sum property of the triangle.

What is obtuse shape?

An obtuse-angled triangle is a triangle in which one of the interior angles measures more than 90° degrees. In an obtuse triangle, if one angle measures more than 90°, then the sum of the remaining two angles is less than 90°.

## Can a scalene triangle also be obtuse?

A scalene triangle can be acute-angled or obtuse-angled or right-angled.

## What is called scalene triangle?

A scalene triangle is a triangle that has all its sides unequal in length and all its angles unequal in measure.
