# Sixty Degrees and Other Angles in Geometry

In geometry, angles can be measured in two ways. The first way is in terms of degrees, with a full circle being 360 degrees. The second way is in terms of radians, with a full circle being 2π radians. An angle of 60 degrees is therefore equal to π/3 radians.

There are 90 degrees in a right angle, 180 degrees in a straight angle, and 360 degrees in a full angle. Other angles are named by the number of degrees they contain, with the symbol ° after the number, such as 45°. A right angle is an angle that measures exactly 90°. It is called a right angle because it forms a square corner, like the corner on a right-angled triangle. A right angle is denoted by the small raised square symbol shown here: ?

Angles that are less than 90° are acute angles. Angles that are more than 90° but less than 180° are obtuse angles. An angle of 180° is called a straight angle because it appears as a straight line when drawn on paper. When two lines intersect at a point and form an angle greater than 180° but less than 360°, this is called a reflex angle. Angles that are greater than or equal to 360° (for example, 540°) but less than 720° are called exteriors angles on the same side as the interior angles.
