Properties of Right Angles:

1. A right angle measures exactly 90 degrees.
2. It can be formed by perpendicular lines, where each line meets at a 90-degree angle.
3. The sum of two right angles is 180 degrees.

Examples of Right Angles:

Some common examples of right angles include:

• The corners of a square or a rectangle
• The intersection of the floor and a wall in a room
• The hands of a clock at 3:00

Study Guide:

When studying right angles, it's important to understand the following concepts:

1. Identifying right angles in geometric shapes and everyday objects.
2. Understanding the relationship between right angles and perpendicular lines.
3. Using a protractor to measure and draw right angles.
4. Calculating the sum of angles in a shape that contains right angles.

Practice drawing and identifying right angles in different shapes and objects to reinforce your understanding of this concept.
