Right Angle
A right angle is a type of angle that measures exactly 90 degrees
A right angle is a type of angle that measures exactly 90 degrees. It is formed when two lines or line segments intersect each other and one of the resulting angles is equal to 90 degrees.
In geometry, a right angle is often symbolized by a small square in the corner where two lines meet. This symbol indicates that the angle is a right angle.
A right angle is considered a basic and important angle in mathematics. It is used in various applications, such as calculations involving triangles, perpendicular lines, and rectangular shapes.
One key property of a right angle is that its two arms, or lines, are perpendicular to each other. This means that they intersect at a 90-degree angle, forming four 90-degree angles in total.
The sum of all angles in a right angle is 180 degrees, so the remaining angle opposite the right angle would measure 90 degrees as well. Together, these two angles form a straight angle.
Right angles are commonly used in solving problems involving trigonometry, Pythagorean theorem, and calculating angles within shapes. They are also frequently found in architectural and engineering designs, where right angles are crucial for maintaining stability and creating symmetry.
In summary, a right angle is an angle that measures exactly 90 degrees. It has two perpendicular lines intersecting each other, forming four 90-degree angles in total. Right angles are important in geometry and various other mathematical applications.
