 # Question: Can A Triangle Have 2 Obtuse Angles?

## Can a triangle have two obtuse angles?

Answer and Explanation: No, a triangle cannot have 2 obtuse angles.

The definition of an obtuse angle is an angle with a measure that is greater than 90°..

## Can a triangle have one right angle?

Ans- No a triangle cannot have more than one right angle as if there are 2 right angles the their sum will be 180° and the third angle will exceed the sum.

## Can a triangle have 3 right angles?

No, real, triangle can have three right angles. … The sum of the angles formed must equal 180° and the sum of the length of two sides must be greater than the length of the third.

## How do you classify acute obtuse and right triangles?

Use the side lengths to classify the triangle as acute, right, or obtuse. Classify the triangle as acute, right, or obtuse. Compare the square of the length of the longest side with the sum of the squares of the lengths of the two shorter sides.

## What is the maximum number of right angles a triangle can have?

Explanation: A triangle has 180o as the sum of all its internal angles, no more, no less. If one angle is 90o , then you can have two 45o angles, one 30o and a 60o , an 81o and a 9o – pretty much any combination of numbers adding up to 90 to make the total 90+90=180 .

## What is the measure of the largest angle in a right angle triangle?

Correct answer: Given that it is a right triangle, either angle A or B has to be 90 degrees. The other angle then must be less than 30 degrees, given that C is greater than 60 because there are 180 degrees in a triangle.

## How many acute obtuse and right angles are in a triangle?

Acute, Obtuse, and Right Trianglesright angles (exactly 90°)obtuse angles (more than 90°, less than 180°)acute angles (less than 90°)Right triangles have exactly one right angle.Obtuse triangles have exactly one obtuse angle.Acute triangles have three acute angles. In other words, ALL the angles are acute.

## Can a triangle have a right angle and an acute angle?

Explanation: A right triangle can, and must, have exactly two acute angles. … As a right triangle has one angle equal to 90∘ , this means the sum of the remaining two angles must be 180∘−90∘=90∘ . Thus, both of the remaining two angles must have a measure less than 90∘ and therefore must be acute.

## Why can a triangle only have one right angle?

Explanation: Since the sum of all angles in any triangle is equal to 180o , so there can be only one right angle if all other angles are to be greater than zero. So the angle C would have to be zero, which is impossible.

## Can a triangle be acute and right?

If any angle becomes 90 degrees or more, it is not an acute triangle. In any triangle, two of the interior angles are always acute (less than 90 degrees)*, so there are three possibilities for the third angle: Less than 90° – all three angles are acute and so the triangle is acute. Exactly 90° – it is a right triangle.

## What type of triangle has 3 unequal sides?

(ii) Isosceles triangle: If two sides of a triangle are equal, then it is called an isosceles triangle. (iii) Scalene triangle: if none of the three sides of a triangle are equal to each other, it is called a scalene triangle. Properties of the scalene triangle: All angles of a scalene triangle are unequal.

## What is the measure of the largest angle in a right triangle?

The largest angle is 5 times the smallest angle, so the largest angle is 5x degrees. So the smallest angle measures 24 degrees….wordscheckThis is a triangle: do the angles all add up to 180 degrees?24 + 36 + 120 = 1802 more rows
