# What is an angle of 0 called? ### 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 :

1. Place the origin of the protractor on the vertex of theangle.
2. You must align the lubber line of the protractor with one of the sides of theangle. …
3. We read the value of theangle 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”.
