[size=200][color=#0000ff][size=150] Two angles are [b]COMPLEMENTARY[/b] if the sum their measures is 90˚and [b]SUPPLEMENTARY[/b]if the sum is 180˚. [/size][/color][/size]
#2)[br]1. Complementary, supplementary, or neither?[br]a) 70˚ and 110˚[br]b) 23˚ and 57˚[br]c) 17˚ and 73˚

#3) Find the COMPLEMENT and the SUPPLEMENT for:[br]a) 20˚
b) x˚
c) (90-m)˚
d) (180-t)˚
[size=200][color=#0000ff][b]Adjacent angles [/b]are two angles that share a common vertex and a common side, but have no common interior points.[/color][/size]
[size=150][color=#0000ff]Complementary and supplementary angle pairs can be adjacent or nonadjacent.[/color][/size]
