Angles in Life Project
Lizzy Holbrook
Acute, Right, Obtuse•Acute: less than 90 degrees.•Right: internal angle equal to 90 degrees.•Obtuse: more than 90 degrees but less than 180 degrees.
Complimentary Angles•Two angles whose measure has a sum of 90 degrees.
Supplementary Angles•Two angles whose measure has a sum of 180 degrees.
A Bisected Angle•Line which cuts an angle into two equal halves.
Vertical Angles•Two non adjacent angles formed by two intersecting lines.•Always congruent.
A Linear Pair•Pair of adjacent angles whose noncommon sides are opposite rays.•Measures to 180 degrees.
Opposite Rays•Two rays with a common endpoint that point in opposite direction and form a straight line
