Identify and Classify Angles (Acute, Right, Obtuse)

Angles are formed when two lines meet at a point, and understanding the different types of angles helps us in geometry and daily life. There are three main types of angles:

Acute Angle:

An acute angle is an angle that is smaller than 90 degrees. It is sharp and narrow, often seen in the corners of certain shapes.

Example: An angle of 30° is an acute angle.

Right Angle:

A right angle is an angle that measures exactly 90 degrees. It forms a perfect square corner, like the corners of most buildings or books.

Example: The corner of a page in a book is a right angle (90°).

Obtuse Angle:

An obtuse angle is an angle that is greater than 90 degrees but less than 180 degrees. It is wide and larger than a right angle.

Example: An angle of 120° is an obtuse angle.

Visual Examples:

• Acute Angle: A sharp angle like the tip of a slice of pizza.
• Right Angle: A corner of a square or a piece of paper.
• Obtuse Angle: The angle between the hands of a clock at 10:10.

Now, let's test your understanding of acute, right, and obtuse angles!
