## 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 an example of obtuse?

The definition of obtuse is someone who is slow to understand things. An example of obtuse is someone who listens to a joke but doesn’t understand the punchline. The definition of obtuse is something that isn’t sharp. An example of obtuse is a child’s pair of scissors.

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

## What is a obtuse triangle with examples?

If one angle is greater than 90° and the other two angles are lesser along with their sum being lesser than 90°, we can say that the triangle is an obtuse triangle. For example, ΔABC has these angle measures ∠A = 120°, ∠A = 40°, ∠A = 20°. This triangle is an obtuse triangle because ∠A = 120°.

## How do you describe an obtuse angle?

1a : not pointed or acute : blunt. b(1) of an angle : exceeding 90 degrees but less than 180 degrees.

## What is a real life example of a straight angle?

A real-life example of a straight angle is when a clock reads 6:00pm. A clock is made up of two different hands.

## Why is obtuse an insult?

Abstruse comes from a Latin word meaning “concealed, hidden, secret.” In English it means “difficult to understand.” Obtuse comes from a Latin word meaning “blunt, dull, stupid.” “Obtuse angles” in geometry are not stupid; they are blunt. An angle “greater than 90 degrees and less than 180 degrees” is an obtuse angle.

## What does it mean if someone calls you obtuse?

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 7 types of angles?

The rays making an angle are called the arms of an angle and the common end point is called the vertex of an angle. There are 7 types of angles. These are zero angle, acute angle, right angle, obtuse angle, straight angle, reflex angle, and complete angle.

## What is the meaning of 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.

## Why is it called an obtuse angle?

Two lines that form a right angle are said to be normal, orthogonal, or perpendicular. An angle larger than a right angle and smaller than a straight angle (between 90° and 180°) is called an obtuse angle (“obtuse” meaning “blunt”).

## What are the different names for obtuse angles?

Obtuse Angles. Different Angles have different names: An Obtuse Angle is more than 90° but less than 180°. All the angles below are obtuse angles:

## How big can an obtuse angle be, Socratic?

An Obtuse Angle is more than 90° but less than 180°.

## Which is smaller the reflex angle or the obtuse angle?

Remember to look carefully at which angle you are being asked to name. The obtuse angle is the smaller angle. It is more than 90° and less than 180°. If you choose the larger angle you have a Reflex Angle (more than 180° but less than 360°) instead:

## How big is an obtuse angle in a circle?

Visually, this angle is more than a quarter of a circle but less than half of a circle. So, if we divide a circle into four parts, an obtuse angle will always occupy between 1/4 and 1/2 of a circle. There is always an obtuse angle within an obtuse triangle.

## What do obtuse angles look like?

Obtuse is defined as blunt, referring to the less pointy characteristic of an obtuse angle. An obtuse angle looks like you are opening a book, before the front cover hits the table, but after the point where it would close if you let the cover go.

## How much does an obtuse angle equal?

Firstly an obtuse angle is an angle which is greater than 90 degrees. This method could also be used to divide an acute angle into four equal parts. An acute angle is an angle less than 90 degrees. The figure above shows an obtuse angle divided into 4 equal parts.

## What are facts about acute angles?

• One acute angle will always measure between 0° 0 ° and 90° 90 °.
• or equal to a right angle.
• Two acute angles can be complementary angles (adding to 90° 90 ° ).
• Two acute angles alone cannot sum to make a straight angle (180° 180 ° ).

## What are the different kinds of angles?

Types of angles. There are six different types of angles – acute, right, obtuse, straight, reflect and revolution angles. Each of these angles is formed by the sizes made by two rays. The angles are classified according to their sizes.
