Answer 1

ANY point on the perpendicular bisector AC will be equidistant from B and D.

Answer 2

so #1-2 are true?

Answer 3

1) is True.

If E is ON the perpendicular bisector AC, then angle EBD = angle EDB. But if E is NOT on AC then 2) is False.

Answer 4

ok and #3 would be false or no

Answer 5

3) False. The two angles mentioned are not adjacent to each other.

Answer 6

do you know how to do # 4

Answer 7

In how many ways can 2 points be selected from the 4 points A,E.M and C?

Answer 8

3

Answer 9

No. 2 points be selected from the 4 points in 4C2 ways. What is 4C2 = ?

Answer 10

4C2 = 4! / (2! * 2!) = 4*3 / 2 = 6 ways.
The four points are A, E, M and C. You can select any two points in the following way:
AE
AM
AC
EM
EC
MC
(for a total of 6 ways). Out of these 6 ways, how many are perpendicular bisectors?

Answer 11

2 ?

Answer 12

AE (not a perpendicular bisector)
AM (yes)
AC (yes)
EM (no)
EC (no)
MC (yes)

3 out of 6 are perpendicular bisectors. Therefore, the probability is ?

Answer 13

1/2

Answer 14

yes.
