Question

Mention the types of angles and their measures

Answer 1

Angles can be classified into the following types:
★Acute => any angle whose measure is more than 0° but less than 90°Eg: 89° 
★Right => angle whose measure is always 90°
★Obtuse => any angle whose measure is more than 90 but less than 180°Eg: 91°... 179°
★Straight => angle whose measure is always 180°
★Reflex => angle whose measure is more than 180° but less than 360°Eg: 181°... 359°
★Complete => angle whose measure is always 360°

Answer 2

Acute angles=<90°
Supplementary angles = sum of the two angles will be 180°.
Right angle = An angle whose measure is 90 degrees.
Obtuse angle = An angle whose measure is bigger than 90 degrees but less than 180 degrees. Thus, it is between 90 degrees and 180 degrees.
Straight angle = An angle whose measure is 180 degrees.Thus, a straight angle look like a straight line.
Reflex angle = An angle whose measure is bigger than 180 degrees but less than 360 degrees.
Adjacent angles = Angle with a common vertex and one common side.
Complementary angles = Two angles whose measures add to 90 degrees. Angle 1 and angle 2 are complementary angles because together they form a right angle.
Vertical angles = Angles that have a common vertex and whose sides are formed by the same lines. The following(angle 1 and angle 2) are vertical angles.
Alternate interior angles = Pairs of interior angles on opposite sides of the transversal.
Alternate exterior angles = Pairs of exterior angles on opposite sides of the transversal.
Corresponding angles = Pairs of angles that are in similar positions.
