Angle

What is an Angle?

An angle is a shape made when two lines meet at a point. The point where they meet is called the vertex. Angles are all around us! We see them in buildings, art, and even in sports.

Angles help us measure how much something turns. We use a special word called degrees to measure angles. A full circle has 360 degrees. This shows us how much something can turn all the way around.

Fun Angle Facts

Angles come in many sizes. A right angle is 90 degrees. It looks like the corner of a book or a window. When two lines form a right angle, they are called normal, orthogonal, or perpendicular.

We can also have angles smaller than a right angle. These are called acute angles. They are less than 90 degrees. Think of a thin slice of pizza — the pointy part makes a small angle.

Angles bigger than a right angle but smaller than a straight line are obtuse angles. They are more than 90 degrees but less than 180 degrees.

Angles in Our World

Angles are important in many things we do. Builders use angles to make strong structures. Artists use angles to draw shapes and pictures. Even in sports, angles help players throw balls or kick goals.

Angles also help us understand the world around us. When we look at the stars, we use angles to find where they are in the sky. Geography uses angles to locate places on Earth.

Angles make our world interesting and help us solve many problems. Next time you look around, try to spot some angles!
