Right Angles

In geometry, an angle is the figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle. A right angle is a special type of angle that measures exactly 90 degrees. When two lines or line segments intersect at a 90-degree angle, they form a right angle.

To identify a right angle, look for the small square symbol in the corner of the angle. This symbol is called a "box," and it indicates that the angle is a right angle.

Right angles are commonly found in everyday objects and shapes, such as the corners of a square, rectangle, or the intersection of two perpendicular lines. They are also important in understanding the concept of perpendicular lines, as two lines that meet at a right angle are said to be perpendicular to each other.

Understanding right angles is foundational for learning about angles, shapes, and geometry. It is an important concept for students to grasp as they progress through their math education.

Overall, right angles are an essential element of geometry, and recognizing them is fundamental for understanding the properties of shapes and angles.
