True or False 15. (True or False) Any 3 distinct points are always coplanar.
16. (True or False) Any 2 distinct circles are always coplanar.
17. (True or False) If 2 lines intersect once then the lines are coplanar.

18. (True or False) Two lines that are skew can sometimes intersect.

19. (True or False) An angle and a circle can have more than 3 intersections

20. (True or False) Two distinct circles can have more than 2 intersections.

21. (True or False) Any given line and point are always coplanar.

15. True

16. False

17. True

18. False

19. True

20. False

21. True

Step-by-step explanation:

15. The three points can be taken as being two points on a line adjacent to a point which always forms a plain when the ends of the line are connected to the point

16. The two circles can be on different planes

17. With one line fixed, the other line can be rotated until both lines are in the flat plane

18. The definition of skew lines are lines in different planes that are not parallel and that do not intersect

19. Whereby the angle crosses the circumference of the circle twice, the number of intersections = 4

20. Two distinct circles can only intersect twice

21.  A plane can always be drawn with any three points

b) 36

step-by-step explanation:

18 times 2 is 36
