## What Are Obtuse Angles?

Contents

#### What is an obtuse angle example?

Obtuse Angle Degree – Now we know that an angle that measures less than 180 degrees but more than 90 degrees is an obtuse angle. Some examples of obtuse angle degrees are 110°, 135°, 150°, 179°, 91°, and more. Hence, all angles that lie in the range of 90° to 180° are obtuse angles.

### Can an obtuse angle be 180?

An obtuse angle cannot be 180 degrees. The definition of an obtuse angle is that it is greater than 90 degrees and less than 180 degrees. So the largest measure of an obtuse angle can be 179 degrees. An angle measuring 180 degrees is called a straight angle.

### Are obtuse angles 90 degrees?

Acute angles measure less than 90 degrees. Right angles measure 90 degrees. Obtuse angles measure more than 90 degrees. Learn about angles types and see examples of each.

#### How do you identify an obtuse angle?

What is Obtuse Angle? – 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°. In the given figure, ∠XYZ shows an obtuse angle. It is an obtuse angle as it measures more than 90 degrees as shown: Some more examples of obtuse angle Here, in Fig: 01, ∠DOQ forms an obtuse angle. And, in Fig: 02 and Fig: 03 ∠ACB and ∠ABC form obtuse angles respectively.

## What angle is 270 degrees?

Angles are formed by two rays that begin at the same point. Knowledge of angle relationships such as complementary and supplementary angles, adjacent angles and sum of the angles of a triangle (they add upto 180 degrees) are necessary in finding missing angles in problems.

An angle whose measure is equal to 90° is called a right angle, A 180° angle is called a straight angle, Angles such as 270 degrees which are more than 180 but less than 360 degrees are called reflex angles, A 360° angle is called a complete angle, Drawing angles, angle measurement need a protractor.

### Is a obtuse 45 degrees?

Obtuse Angle – Obtuse Angle An obtuse angle is the opposite of an acute angle. It is the angle which lies between 90 degrees and 180 degrees or in other words; an obtuse angle is greater than 90 degrees and less than 180 degrees. The figure above illustrates an obtuse angle.

#### Is 80 degrees obtuse?

Angles between 0 and 90 degrees (0° Angles between 90 and 180 degrees (90°.

#### What angle is 360 degrees?

The 360-degree angle is a full angle or a complete angle as it forms a circle around a point. It is exactly double the straight angle (180-degree angle). If we talk about a real-life example of a 360-degree angle, then a perfect example is the angle between the two hands of a clock at 12 o’clock.

### What is a 150 degree angle called?

Acute angle-an angle between 0 and 90 degrees. right angle-an 90 degree angle. obtuse angle-an angle between 90 and 180 degrees.

## What do you call a 240 degree angle?

An angle of measure 240∘ is called a reflex angle.

### What is a 225 degree angle called?

Acute Angle – An angle less than 90 degrees. Right Angle – An angle that is exactly 90 degrees. Obtuse Angle – An angle more than 90 degrees and less than 180 degrees. Straight Angle – An angle that is exactly 180 degrees. Reflex Angle – An angle greater than 180 degrees and less than 360 degrees.

#### Is 5 o clock an obtuse angle?

Answer: At 5 o’clock, the hour hand is at 5 and the minute hand is at 12. So the angle between the two hands of the clock at 5 o’clock is 5*30 = 150 deg, which is an obtuse angle and not an acute angle. The other reflex angle is 360–150 = 210 degrees. Step-by-step explanation:

## Which shapes have 2 obtuse angles?

The trapezoid has 2 acute angles and 2 obtuse angles. It belongs in the group ‘acute and obtuse.’ Remember to look at all of the angles in a shape before you put it in a group.

## What is a number less than 180 that rounds to 180?

9 Solution Possible answers: 175, 176, 177, 178, 179 ; Possible answers: 181, 182, 183, 184; Any number from 175 through 184 will round to 180.

## What is the name of a 60 degree angle?

What do You Call a 60-Degree Angle? – An angle whose measure is more than 0° but less than 90° is called an acute angle, Angles measuring 30°, 40°, 60° are all acute angles. Therefore a 60-degree angle is known as an acute angle.

## Can a triangle have an obtuse angle?

Hence, a triangle can have only one obtuse angle.

### What angle is 45 degree?

A 45-degree angle is an acute angle. It is half of the right angle or 90-degree angle. An angle bisector of a 90-degree angle forms two equal angles of 45 degrees each. The 45-degree angle can be seen in so many places in our day-to-day life, such as in scissors, doors, windows, etc. It is also seen as the angle formed by the diagonal of a square with its sides.

### Which shapes have 2 obtuse angles?

The trapezoid has 2 acute angles and 2 obtuse angles. It belongs in the group ‘acute and obtuse.’ Remember to look at all of the angles in a shape before you put it in a group.

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

Folding Mobiles and laptops are also good examples of an obtuse triangle. Unfold the screen of the mobile or laptop completely. There, you will see a newly formed triangle. In the triangle, you will see an obtuse angle between the base of the mobile or laptop and the screen.

#### Is an obtuse angle 100 degrees?

Conclusion – An obtuse angle is an angle that is greater than 90 degrees but less than 180 degrees. An obtuse angle is also called a reflex angle. A reflex angle is formed when the arms of an angle point in opposite directions. The degree of an obtuse angle is between 91 and 179 degrees. The most common example of an obtuse angle is a right angle. A right angle has a degree of 90 degrees.

- Some other examples of obtuse angles include:
- 135 degree angle 145 degree angle
- 155 degree angle
