Question

9) How many angles are greater than 90° in the given figures?​

Answer 1

Step-by-step explanation:

There are five types of angles:

Acute= Angles more than 0° but less than 90°

Obtuse= Angles more than 90° but less than 180°

Right = Angles with a measure of 90°

Straight= angles exactly measuring 180°

Reflex= Angle greater than 180° and less than 360°

Full= Angle exactly 360°

Zero = Angle exactly 0° (when both the arms are at same position).

As stated above, if the measure of an angle is greater than 90° but less than 180° is an Obtuse Angle
