We know that the Circumcenter is the intersection of a triangle's right (perpendicular) bisectors. Once you have found two of these you can determine their point of intersection.
It is a proven mathematical concept that the third perpendicular bisector will also cross through this intersection point. While it is not necessary to construct all three it is often done so to verify that the intersection of the first two perpendicular bisectors was in fact correct.
Answer:
1. AB=CB def of isosceles triangle
2. AD=CD DEF of median
3. BD=DB reflexive property
4. ADB=CDB SSS
Step-by-step explanation:
ummmm its just the right answer trust
Total number of cards = 52
Total number of kings or queens = 8
P(King or Queen) = 8/52 = 2/13
------------------------------------------------------------
Answer: The probability is 2/13.

The answer would be x = -9
Answer:
60 km/hr
Step-by-step explanation:
100+100
_______ =3x
8
3x= 200/8
x=200/24 mps
=30mph
final speed is 60km/hr because its 2x's more =2*30=60
