Presentation Transcript

  1. Bellringer • Factor: 2x2 +2x -4 • A. (2x-1) (x+4) • B. (2x-2) (x+2) • C. (x+2) (x-2) • D. (X-4) (x+1)

  2. Complementary and Supplementary angles 2-3

  3. Complementary angles • Two angles are complementary angles if the sum of their measures is 90. • Each angle is the complement of the other

  4. Supplementary angles • Two angles are supplementary angles if the sum of their measures is 180 • Each angle is the supplement of the other

  5. Angle Addition Postulate • If R is in the interior of <PQS, then m<PQR + m<RQS = m<PQS P R Q S

  6. Terms • Adjacent angles are two angles that lie in the same plane, have a common vertex, and a common side. • A Linear Pair is a pair of adjacent angles whose non common side are opposite rays.

  7. Theorems • A theorem is a true statement that follows from other true statements. • Supplement Theorem If two angles form a linear pair, then they are supplementary angles. • Complement Theorem If the noncommon sides of two adjacent angles form a right angle, then the angles are complementary angles

  8. Homework • Pg 70 #s 2-38 evens
