Vocabulary  Complementary  Supplementary  Adjacent angles

3.2 Types of Angles Integ. Math

 Two angles are complementary if the sum of their measures is 90°.  Two angles are supplementary if the sum of their measures is 180°

Naming Angles  Name the straight angle.  Name all of the obtuse angles.  Name all of the acute angles.  Name all of the right angles. A B C D E F G

 To make a decorative tile border, two tiles must be joined as shown in the figure. The square bracket ( ) indicates the <UYW is a right angle. Find m<UYV. U W Y V (a+42)° a°

 The measure of <JKL is 34° more than the measure of its complement. Find <JKL.

 The measure of <MJK is 8° more than twice as much as is supplement. Find the m<MJK.
