angle
Definition
An angle is the space between two lines that meet at a point. The point where the two lines meet is called the vertex of the angle.
Angles are measured in degrees. A full circle is 360 degrees, so a straight angle is 180 degrees.
There are many different types of angles. Some common types of angles include acute angles, obtuse angles, and right angles.
Acute angles are angles that are less than 90 degrees.
Obtuse angles are angles that are more than 90 degrees but less than 180 degrees.
Right angles are angles that are exactly 90 degrees.
Angles are used in many different ways in science and everyday life. They are used to measure the direction of objects, to calculate the speed of objects, and to design structures.
