The above angles are read "angle ABC" and "angle DEF." Your geometry studies have shown you acute, right and obtuse angles. The angles are classified according to their sizes. Straight angle: The angle that is 180° is a straight angle, ∠AOB in the figure below. It's time we closely examined an angle. Edit. Names of angle relationship DRAFT. Save. Let’s look at these six different types of angles: The common endpoint of the angle is called the vertex. Angles ∠1 and ∠2 are adjacent. Angles are named in two ways. Equilateral triangle – 3 equal sides 2. Hexagon – 6 sides 7. Angles are also formed by the intersection of two planes. You can learn about congruent, adjacent, vertical, corresponding, and alternating angles, too. Adjacent angles: Angle with a common vertex and one common side. If you're behind a web filter, please make sure that the domains *.kastatic.org and *.kasandbox.org are unblocked. Equilateral: \"equal\"-lateral (lateral means side) so they have all equal sides 2. Quadrilateral – 4 sides 1. Angles are formed by two rays (or lines) that begin at the same point or share the same endpoint. Angle FPA would be this angle right over here, which is also clearly a different angle. The point at which the two rays meet (intersect) is called the vertex. Angle-related Symbols. Right angle: The angle that is 90° is a Right angle, ∠C as shown below. In this section we know about definition of angle in geometry and its types of angles like Interior and Exterior of an angle, Zero Angle, Acute Angle, Right Angle, Obtuse angle, Straight Angle, Reflex Angle & Complete angle. But in geometry an angle is made up of two rays that have the same beginning point. Here's how!
