# FAQ: What Is Obtuse Angle In Mathematics?

## What does obtuse angle mean?

An obtuse angle is a type of angle that is always larger than 90° but less than 180°. In other words, it lies between 90° and 180°.

## What shapes are obtuse angles?

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°.

## Which triangle is obtuse?

An obtuse triangle is one that has an angle greater than 90°. Because all the angles in a triangle add up to 180 °, the other two angles have to be acute (less than 90°). It’s impossible for a triangle to have more than one obtuse angle.

## What is obtuse angle with diagram?

## What are the 7 types of angles?

The 7 types of angles are: right angles, acute angles, obtuse angles, straight angles, reflex angles, full angles, and complementary angles.

## Why is obtuse an insult?

Obtuse, which comes to us from the Latin word obtusus, meaning “dull” or “blunt,” can describe an angle that is not acute or a person who is mentally “dull” or slow of mind. The word has also developed a somewhat controversial sense of “hard to comprehend,” probably as a result of confusion with abstruse.

## What are the 5 types of angles?

Types of Angles – Acute, Right, Obtuse, Straight and Reflex

• Acute angle.
• Right angle.
• Obtuse angle.
• Straight angle.
• Reflex angle.

## What is a real life example of an obtuse angle?

Obtuse angles are seen on most house rooftops, as the two roof surfaces slope down from it. Other real world examples of an obtuse angle include the angle between the screen and the base of an opened laptop, a hockey stick, an accordion hand fan and between the wings of a boomerang.

## What is a shape with 2 obtuse angles?

Here is an example of a trapezoid. Notice that this trapezoid has two acute angles and two obtuse angles.

## 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.

## What are the properties of obtuse triangle?

Obtuse Angled Triangle Properties The sum of the two angles other than the obtuse angle is less than 90 degrees. The side opposite to the obtuse angle is the longest side of the triangle. An obtuse triangle will have one and only one obtuse angle. The other two angles are acute angles.

## How do you classify a triangle?

Triangles can be classified either according to their sides or according to their angles. All of each may be of different or the same sizes; any two sides or angles may be of the same size; there may be one distinctive angle.

## How do you solve an obtuse angle?

Square the length of both sides of the triangle that intersect to create the obtuse angle, and add the squares together. For example, if the lengths of the sides measure 3 and 2, then squaring them would result in 9 and 4. Adding the squares together results in 13.

## What kind of angle is 180 degrees?

Angles that are 90 degrees (θ = 90°) are right angles. Angles that are 180 degrees (θ = 180°) are known as straight angles. Angles between 180 and 360 degrees (180°< θ < 360°) are called reflex angles. Angles that are 360 degrees (θ = 360°) are full turn.
