A right angle measures 90 degrees, while a straight angle measures 180 degrees.
A right angle is characterized by its L-shape, formed when two lines intersect to create a quarter turn. This is a crucial concept in geometry, as it sets the foundation for understanding other angles. You can often see right angles in various shapes, like squares and rectangles, where corners meet at right angles.
On the other hand, a straight angle represents a complete half-turn. It is formed when two rays point in exactly opposite directions, creating a straight line. This type of angle is significant in numerous applications, such as in the measurement of angles and in design layouts.
