Right Angle

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

Properties of a Right Angle:

1. A right angle measures exactly 90 degrees.
2. It forms a perfect L-shape.
3. It is half of a straight angle (180 degrees).

Examples of Right Angles:

Here are some examples of objects or shapes that have right angles:

• The corners of a book or a piece of paper
• The corners of a square or a rectangle
• The hands of a clock at 3 o'clock
• A perfectly vertical line meeting a perfectly horizontal line

Study Guide:

When studying right angles, it is important to remember the following key points:

1. Identify right angles in everyday objects and shapes around you.
2. Understand that a right angle measures exactly 90 degrees.
3. Practice drawing right angles using a protractor or by estimating the angle.
4. Recognize the relationship between right angles and other types of angles, such as acute angles and obtuse angles.

Now that you have a better understanding of right angles, you can start practicing and identifying them in different contexts!
