(1)Acute angle - An acute angle measure between 00 and 900.
(2)Right angle - A right angle is exactly equal to 900.
(3)Obtuse angle - An angle greater than 900 but less than 1800.
(4)Straight angle - A straight angle is equal to 1800.
(5)Reflex angle - An angle which is greater than 1800 but less than 3600 is called a reflex angle.
(6)Complementary angles - Two angles whose sum is 900 are called complementary angles.
(7)Supplementary angle - Two angles whose sum is 1800 are called supplementary angles.
(8)Adjacent angles - Two angles are adjacent, if they have a common vertex, a common arm and their non common arms are on different sides of common arm.
(9)Linear pair - Two angles form a linear pair, if their non-common arms form
a line (a straight angle).
(10)Vertically opposite angles - Vertically opposite angles are formed when two lines intersect each other at a point.
