  1. 2. A straight line that touches a circle at only one point. This point is called the point of tangency.
  2. 4. an arc that measures more than 180. It is also less then 360 and is found by 360 minus its associates minor arc (uses 3 letters)
  3. 7. An angle whose vertex is on the circle and sides contain chords. The measure of an inscribed angle is 1/2 of the measure of its intercepted arc.
  4. 8. A straight line that intersects a circle. It intersects at exactly two points
  5. 12. The sum of the areas of all of the faces. This does include the bases.
  6. 14. Name a shape with 3 sides. All angles add up 180.
  7. 15. A line segment throughout the entire circle passing through the center. This is double the length of the radius.
  8. 16. A quadrilateral having only one pair of parallel sides. The sides that are parallel are called the bases and the non- parallel sides are called the legs.
