Right Angles

A right angle is an angle that measures exactly 90 degrees. It is represented by a small square in the corner of the angle, like this: size: 24px;">∛.

Properties of Right Angles:

1. Measurement: A right angle measures 90 degrees.
2. Perpendicular Lines: When two lines intersect to form a right angle, they are said to be perpendicular to each other.
3. Shape: Right angles are often found in geometric shapes such as squares, rectangles, and right-angled triangles.

Examples of Right Angles:

Here are some examples of right angles in different contexts:

• A square has four right angles, each measuring 90 degrees.
• The corners of a book form right angles.
• The hands of a clock form a right angle at 3 o'clock and 9 o'clock.

Identifying Right Angles:

To identify a right angle, look for the small square symbol (size: 24px;">∛) at the vertex of the angle or use a protractor to measure the angle and check if it is exactly 90 degrees.

Study Guide:

When studying right angles, make sure to:

• Understand the definition and properties of a right angle.
• Practice identifying right angles in different shapes and objects.
• Learn how to measure and draw right angles using a protractor.
• Apply the concept of right angles to solve geometric problems and real-life scenarios.

Remember, right angles are fundamental to understanding geometry and are widely used in various fields such as architecture, engineering, and design.
