Ответ:
• An angle is formed when two lines or rays or line segments meet or
intersect.
• When the sum of the measures of two angles is 90°, the angles are
called complementary angles. Each of them is called complement of
the other.
• When the sum of the measures of two angles is 180°, the angles are
called supplementary angles. Each of them is called supplement of
the other.
• Two angles are called adjacent angles, if they have a common vertex
and a common arm but no common interior points.
• A linear pair is a pair of adjacent angles whose non-common sides
are opposite rays.
• When two lines intersect, the vertically opposite angles so formed
are equal.
• When two lines are intersected by a transversal, eight angles are
formed. These angles can be classified as 4 interior angles, 4 exterior
angles, 4 pairs of corresponding angles, 2 pairs of alternate interior
angles, 2 pairs of alternate exterior angles and two pairs of interior
angles on the same side of the transversal
