## Can there be an obtuse angle in an isosceles triangle?

An isosceles triangle can have only one obtuse angle. An obtuse angle is an angle greater than 0∘ and less than 180∘ .

## What is an obtuse isosceles angle?

An isosceles obtuse triangle is a triangle in which one of the three angles is obtuse (lies between 90 degrees and 180 degrees) and the other two acute angles are equal in measurement. One example of isosceles obtuse triangle angles is 30°, 30°, and 120°.

**What kind of triangle do you have if it has an obtuse angle which measures more than 90 but less than 180?**

obtuse triangle

An obtuse triangle (or obtuse-angled triangle) is a triangle with one obtuse angle (greater than 90°) and two acute angles. Since a triangle’s angles must sum to 180° in Euclidean geometry, no Euclidean triangle can have more than one obtuse angle.

**How many acute angles are in the isosceles triangle?**

two acute angles

Isosceles. An isosceles triangle can be drawn in many different ways. It can be drawn to have two equal sides and two equal angles or with two acute angles and one obtuse angle.

### What is an acute angled isosceles triangle?

Acute Isosceles triangles are the triangles with all their internal angles being acute angles and only two sides equal to each other in length.

### What is an acute isosceles?

By definition, an acute isosceles triangle will have at least two sides (and at least two corresponding angles) that are congruent, and no angle will be greater than .

**How do you find an obtuse triangle?**

To calculate the angle of an obtuse triangle, you need to square the lengths of the two sides of the triangle that will intersect to make the obtuse angle and add the squares of them. For example – if the two sides of the triangle are 2 and 4, then squaring them will give 4 and 16.

**What triangle can be obtuse?**

An obtuse-angled triangle can be a scalene triangle or isosceles triangle but will never be equilateral since an equilateral triangle has equal sides and angles where each angle measures 60°.

## Which triangle is obtuse?

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°. Here, the triangle ABC is an obtuse triangle, as ∠A measures more than 90 degrees.

## How many acute angles are in an obtuse triangle?

Explanation: An obtuse scalene triangle must have one obtuse interior angle and two acute angles. All triangles have three interior angles with a sum total of degrees.
