A right angle has 90 degrees. Angles are measured on a scale from 0 to 360 degrees. Right angles represent one-fourth of a full 360-degree revolution.
Know MoreRight angles have their own symbol, which is a square in the corner where the two lines of the angle meet. Math has six kinds of angles: acute, right, obtuse, straight, reflex and full. Acute and obtuse angles are defined in relation to right angles, as acute angles are less than 90 degrees and obtuse angles are between 90 and 180 degrees. A straight angle is exactly 180 degrees, and a full angle is exactly 360 degrees. Reflex angles fall between 180 and 360 degrees.
Learn MoreThe interior of a pentagon has five angles totaling 540 degrees. In a regular pentagon – a polygon with five congruent sides and five congruent angles – each angle is 108 degrees. Each exterior angle of a regular pentagon is 72 degrees.
Full Answer >A symmetrical pattern is a pattern in which converging lines form an angle that somewhat resembles an acute angle. When two patterns are symmetrical, one becomes exactly like another when flipped or turned, according to Primary Resources.
Full Answer >A vertex angle refers to the angle that is formed by the two lines crossing at a vertex. When asked for a vertex angle, the intended query is typically for the size of the angle in degrees or radians.
Full Answer >Draw an arc on the vertex of the angle. Then draw two more arcs from the intersection of the previous arc and the two legs in the interior of the angle. Finally draw a straight line through the vertex and the intersection of the last two arcs.
