In various other words, an angle measuring in between 0° come 90° is dubbed an acute angle. ∠ABCin the given number is an acute angle.

You are watching: An angle whose measure is greater than 90 degrees


∠MON presented in adjoining figure is equal to 60°. So, ∠MON is one acute angle.

2. Appropriate Angle:

An edge whose measure up is 90° is called right angle.

In various other words, an edge which measure exactly 90° is dubbed a appropriate angle.

Twolines that accomplish at a appropriate angle are referred to as perpendicular lines.


In the above figure, ∠AOB is a appropriate angle. In this case,we say the the arms OA and also OB room perpendicular to each.

Therefore, ∠AOB displayed in adjoining figure is 90°. So, ∠AOB is a ideal angle.

3. Obtuse Angle:

An edge whose measure up is higher than 90° but less 보다 180° is referred to as an obtuse angle.

In various other words, an edge measuring between 90° to 180° is dubbed an obtuseangle.


∠DOQ displayed in the over figure is an obtuse angle.

4. Right Angle:

An angle whose measure up is 180° is dubbed a straight angle.

In various other words, an edge which measures precisely 180° is called a straightangle.


∠XOY displayed in the over figure is a straight angle. A right angle is equal to two right angles.

5. Reflex Angle:

An angle whose measure is more than 180° yet less 보다 360° is dubbed a reflex angle.


∠AOB displayed in the above figure is 210°. So, ∠AOB is a reflex angle.

6. Zero Angle:

An angle measure up 0° is referred to as a zero angle.

When 2 arms the an angle lie on each other, 0° edge is formed.

Comparision that Angles

An angle whose level measure is better than the degreemeasure of one more angle is a greater angle. Thus, we have the right to say that:
