## How many right angles does a obtuse triangle have?

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.

## Can an obtuse triangle have a right angle?

A **triangle** cannot be **right**–**angled** and **obtuse angled** at the same time. Since a **right**–**angled triangle has** one **right angle**, the other two **angles** are **acute**. Therefore, an **obtuse**–**angled triangle can** never **have a right angle**; and vice versa. The side opposite the **obtuse angle** in the **triangle** is the longest.

## Can a right triangle also be obtuse?

A **right triangle** cannot be **obtuse** because of the sizes of the angles therein. Any **triangle** has three sides, three angles, and three angles that equal

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

A **triangle can have** a **maximum** of 1 **obtuse angle**.

## What is the greatest number of right angles in a triangle?

Explanation: A triangle has **180**o 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**.

## Why can’t a right triangle have an obtuse angle?

When an **angle** of a **triangle** is 90 degrees, the **triangle** cannot **have an obtuse angle**. The other two must each be less than 90 degrees (90 deg + 89 deg + 1 deg = 180 deg). It therefore follows that they must both be less than 90 degrees and so must both be **acute**.

## Can 1 acute and 2 obtuse form a triangle?

Types of **Triangles**. All equilateral **triangles** are equiangular. A right **triangle** will have **1** right angle and **2 acute** angles. An **obtuse triangle** will have **1 obtuse triangle** and **2 acute** angles.

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

Question 945360: A **triangle** cannot **have both an acute angle** and a **right angle**? In a **right triangle**, **BOTH** of the other **angles** MUST be **acute**. An obtuse **angle** (greater than 90 degrees) would make the sum of the **angles** greater than 180 degrees, which is impossible.

## Can a triangle have 2 right angles?

No, a **triangle can** never **have 2 right angles**. A **triangle has** exactly 3 sides and the sum of interior **angles** sum up to 180°. Thus, it is not possible to **have** a **triangle** with **2 right angles**.

## Can an acute triangle be a right triangle?

A **triangle** where all three internal angles are **acute** (less than 90 degrees). Less than 90° – all three angles are **acute** and so the **triangle** is **acute**. Exactly 90° – it is a **right triangle**.

## Do all triangles have right angles?

A **right triangle** may be isosceles or scalene. In an acute **triangle**, **all angles are** less than **right angles**? each one **is** less than 90 degrees. An acute **triangle** may be equilateral, isosceles, or scalene.

## Is it possible to have a right isosceles triangle?

An **isosceles right triangle** is an **isosceles triangle** and a **right triangle**. This means that it has two congruent sides and one **right** angle. Therefore, the two congruent sides must be the legs.

## How many obtuse angles are in a triangle?

There can only be **one obtuse** angle in any triangle. This is because the measures of the interior angles of a triangle always must add up to **180**

## How many right angles does a triangle have?

A triangle can have **one right angle**. A quadrilateral can have four right angles. Sum of Interior Angles = 540′.

## How many angle Can a triangle have?

In a Euclidean space, the sum of angles of a triangle equals the straight angle (**180 degrees**, π radians, **two** right angles, or a half-turn). A triangle has **three angles**, one at each vertex, bounded by a pair of adjacent sides.
