SECTION 1.5Angle Relationships

Adjacent Angles: two angles that lie in the same plane, have a common vertex, and a common side, but no common interior points

Vertical Angles:two nonadjacent angles formed by two intersection lines

Linear Pair: 

pair of adjacent angles whose non­common sides are opposite rays

Complementary Angles:

two angles whose measures have a sum of 90 degrees

Supplementary Angle: 

two angles whose measures have a sum of 180 degrees

Perpendicular:

lines that intersect at right angles (intersect and form 90 degree angles)

Find the measures of two complementary angles if the difference in the measures of the two angles is 12.

Find x and y so that BE and AD are perpendicular.
