### What is an angle of 0 called?

**Angle** bad : **Angle** that measures **0** degree. **Angle** acute : **Angle** better than **0** degree and less than 90 degrees. **Angle** right : **Angle** of 90 degrees. **Angle** obtuse: **Angle** between degrees.

### What are obtuse angles?

The measure of a **acute angle east** smaller than 90°. The measure of a **angle** right **is** 90°. The measure of a **obtuse angle** is between 90° and 180°.

### How do you measure an acute angle?

**Suppose we want measure the value ofacute angle below using a protractorangle :**

- Place the origin of the protractor on the vertex of the
**angle**. - You must align the lubber line of the protractor with one of the sides of the
**angle**. … - We read the value of the
**angle**thanks to the scales of the protractor.

### What is the difference between an obtuse angle and an acute angle?

In mathematics, an obtuse angle is a salient angle whose measure is greater than that of the right angle, in other words an angle whose measure in degrees is between 90° and 180° (i.e. between π /2 and π radians ) . A salient angle whose measure is less than that of the right angle is said to be acute.

### What is obtuse angle?

Obtuse angle. In mathematics, an obtuse angle is a salient angle greater than a right angle, in other words an angle whose measure in degrees is between 90° and 180° (i.e. between π /2 and π radians ). A salient angle less than the right angle is said to be acute. A triangle that has an obtuse angle is said to be obtuse.

### What is the measure of an angle?

Angle in a plane whose measure is between the measure of a right angle and that of a straight angle. In degrees, the measurement of an obtuse angle is between 90° and 180°.

### What is the difference between a right angle and a straight angle?

The angles all have a qualifier based on their measurements. A 90° angle is a “right” angle, as it has been written. Any angle whose measure is between 0 and 90° is said to be “acute”. Any angle whose measure is between ° is said to be “obtuse”. An angle having an exact measure of 180° is said to be “flat”.
