Right Angles

A right angle is an angle that measures exactly 90 degrees. It is often represented by a small square in the corner of the angle.

Properties of Right Angles:

1. Measurement: A right angle measures 90 degrees.
2. Perpendicular Lines: Two lines that form a right angle are called perpendicular lines. This means they intersect at a right angle.
3. Shape: Right angles are found in many geometric shapes, such as squares, rectangles, and right-angled triangles.

Examples of Right Angles:

Here are some examples of where right angles can be found:

• In the corners of a square or rectangle
• Where the floor meets the wall in a room
• The corner of a piece of paper or book
• In the shape of an "L" formed by two intersecting walls

Study Guide:

Here are some key points to remember about right angles:

1. Always measure the angle to check if it is exactly 90 degrees.
2. Look for the small square symbol to identify a right angle in diagrams or shapes.
3. Practice identifying right angles in real-life situations, such as around your home or school.

Understanding right angles is important for geometry and for understanding the properties of shapes and lines. Keep practicing and looking for right angles in your everyday environment to reinforce your understanding of this concept.
