An angle is the amount of rotation between two lines or planes. Angles can be measured using a protractor or by calculating the ratio of the lengths of two line segments. Angles can be used to solve a variety of problems in mathematics and science.

Angle: a figure formed by two rays, or sides, with a common endpoint called the vertex. Acute Angle: an angle that measures between 0 and 90 degrees. Obtuse Angle: an angle that measures between 90 and 180 degrees. Reflect Angle: an angle that measures more than 180 degrees

The angle used in most construction is the 90-degree angle, which is also known as a right angle. The angle of the Earth's axis is 23.5 degrees, which is why we experience the seasonal changes we experience on Earth.
