What's on the worksheet

  1. Find the other arc with the same endpoints and say whether it is minor, major or a semicircle.
    m\overset{\frown}{AB} = 38^\circm\overset{\frown}{CDE} = 251^\circm\overset{\frown}{FGH} = 180^\circm\overset{\frown}{JK} = 179^\circm\overset{\frown}{LMN} = 312^\circ
  2. Find arcs and angles around a circle with five points and four given arcs.
  3. Find every value x can take for a minor arc and for a major arc.
  4. Find the sweep angle between boats on a radar screen at given bearings.
  5. Find the pie chart angles for how 72 students get to school.
  6. Show that arcs across from each other being congruent forces facts about the four points.
