True or False

  1. angleABC and angleCBD are complementary angles.
  2. angleEHB and angleKHJ are adjacent angles.
  3. angleBEF and angleFEG are complementary angles.
  4. angleLKM and angleBKH are vertical angles.

Find the measure of each angle using the figure above.

  1. mangleABC
  2. mangleBEF
  3. mangleBKE
  4. mangleDBE
  5. mangleKBH
  6. mangleJHE

Answer the following questions using the figure below.

Two lines intersect to form 4 angles. The angles are numbered 1, 2, 3, and 4. Angle 2 is 5 times x minus 10 degrees. Angle 3 is 6 times y minus 14 degrees. Angle 4 is 3 times x plus 38 degrees
  1. Find the value of x and then find the measures of angle2 and angle4.
  2. Find the value of y.
  3. The measure of an angle is 12 more than twice its supplement.  Find the measure of each angle.
