Draw the following: Line AB Line segment BC Ray FG LEQ: How do we classify angles? An angle is the union of two rays that share a common endpoint. There are 4 ways to name an angle: CED DEC E 3 Acute angles have measures between 0 and 90 degrees Right angles have measures of exactly 90 degrees (indicated by a small square) Obtuse angles have measures between 90 and 180 degrees Straight Angle – an angle measuring 180 degrees Right angle Straight angle Acute angle Obtuse angle Congruent angles are angles of the same measure(indicated by identical markings) Similar to the ruler postulate, if point B is in the interior of AOC, then mCOB+mBOA=mCOA (<AOC) Vertical angles are opposite congruent angles created by the intersection of two lines <1 and <3 are vertical angles <2 and <4 are vertical angles Adjacent angles are angles that share a common side, common vertex, and no common interior points. <KIH and <KIJ are adjacent angles Complementary angles are two angles who’s measures sum to 90. <TSU and <USV are complementary angles. If m<TSU=42, what is m<USV? <TSU is the complement of <USV Supplementary angles are two angles who’s measures sum to 180. <TSU and <USV are supplementary angles. <TSU is the supplement of <USV. If m<TSU=120, what is m<USV? Use the adjacent angles below to solve the following: m<HOK = 4x-6, m <KOB=6x+2, find x and m<HOK. Line up the bottom of the protractor with a side of the angle and center of angle with center of protractor. Extend the line of the other side and read the degree. p.40-41, 1-8,15,17,19,24-32 odds,43,45
