Right Angle

A right angle is an angle that measures exactly 90 degrees. In geometric terms, it is formed by two perpendicular lines that intersect, creating four 90-degree angles at the point of intersection.

Characteristics of Right Angles:

• A right angle is always exactly 90 degrees.
• It is represented by the symbol ∡
• The sides of a right angle are perpendicular to each other, forming a perfect L-shape.

Examples of Right Angles:

Some common examples of right angles include:

• The corner of a book
• The intersection of two walls
• The corner of a square or rectangle

Study Guide:

To understand and identify right angles, it is important to remember the following key points:

1. A right angle always measures 90 degrees.
2. It forms a perfect L-shape, with perpendicular sides.
3. Look for examples of right angles in everyday objects and surroundings.
4. Practice identifying right angles in geometric shapes and diagrams.
5. Understand the symbol ∡ that represents a right angle.

Understanding right angles is essential in geometry and real-world applications. Recognizing right angles helps in measuring and constructing shapes, understanding architectural designs, and solving various mathematical problems.
