What Are Angles?
Angles are everywhere around us!
An angle is formed when two lines meet at a point. We measure angles in degrees (°). There are four main types of angles you should know: acute, right, obtuse, and straight angles. Let's explore each one!
Acute Angle
Less than 90°
Like a pizza slice!
Right Angle
Exactly 90°
Like a book corner!
Obtuse Angle
Between 90°-180°
Like a reclining chair!
Straight Angle
Exactly 180°
Like a straight line!

Parent Tips 🌟
- Angle scavenger hunt: Make a game of finding different angles around your home. Give points for each type found!
- Hands-on learning: Use popsicle sticks or straws to create different angles and measure them with a protractor.
- Real-world connections: Point out angles in everyday objects like doors (right angles), open books (acute or obtuse), or straight roads (straight angles).
