Right Angle:
An angle formed when the door is opened to form a perfect 'L' shape is known as a right angle. Let's break down why this is the correct answer:
- Definition: A right angle is exactly 90 degrees. It is formed when two lines are perpendicular to each other, creating a perfect 'L' shape.
- Properties: In a right angle, the two lines are perpendicular, meaning they intersect at a 90-degree angle.
- Visual Representation: When a door is opened to form a perfect 'L' shape, one side of the door is vertical, and the other side is horizontal, creating a right angle at the corner where the two sides meet.
- Common Examples: Right angles are commonly seen in everyday objects like corners of rooms, doors, windows, and many architectural structures.
- Importance: Right angles are crucial in geometry and construction as they help in creating perpendicular lines, squares, rectangles, and other shapes.
In conclusion, when a door is opened to form a perfect 'L' shape, it creates a right angle at the corner where the two sides meet. This angle is essential in various fields and is easily identifiable due to its 90-degree measurement.
