Question

write the name of seven angle​

Answer 1

there are only 5 angles .... hope this May helps u

Answer 2

Answer:

1. Acute Angle:

An angle whose measure is less than 90° is called an acute angle.

In other words, an angle measuring between 0° to 90° is called an acute angle. ∠ABC in the given figure is an acute angle.



∠MON shown in adjoining figure is equal to 60°. So, ∠MON is an acute angle.

2. Right Angle:

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

In other words, an angle which measure exactly 90° is called a right angle.

Two lines that meet at a right angle are called perpendicular lines.



In the above figure, ∠AOB is a right angle. In this case, we say that the arms OA and OB are perpendicular to each.

Therefore, ∠AOB shown in adjoining figure is 90°.

So, ∠AOB is a right angle.

3. Obtuse Angle:

An angle whose measure is greater than 90° but less than 180° is called an obtuse angle.

In other words, an angle measuring between 90° to 180° is called an obtuse angle.



∠DOQ shown in the above figure is an obtuse angle.

4. Straight Angle:

An angle whose measure is 180° is called a straight angle.

In other words, an angle which measures exactly 180° is called a straight angle.



∠XOY shown in the above figure is a straight angle.

A straight angle is equal to two right angles.

5. Reflex Angle:

An angle whose measure is more than 180° but less than 360° is called a reflex angle.



∠AOB shown in the above figure is 210°.

So, ∠AOB is a reflex angle.

6. Zero Angle:

An angle measure 0° is called a zero angle.



When two arms of an angle lie on each other, 0° angle is formed.
