Answer:
Step-by-step explanation:
Hi there!
Equation of a circle: where the circle is centered at and r is the radius
Plug in the center (5,7)
Plug in the given point (-2,8) to solve for r²
Therefore, r² is equal to 50. Plug this back into
I hope this helps!
12. the reflexive property of congruence means anything is congruent to itself
13. the transitive property of equality means if 2 things are equal to the same other thing then they are equal to each other
14. Symmetric property of equality means that you can change the order of the equation
15. That's the transitive property of congruence its basically the same as 13 but with segments instead of the measure of angles.
Cool question (Although it is tough somewhat)
1st step is to visualize the change from C to C'
we have C'(8,-3) and C(3,-8) supposedly for C because it doesn't show any real values.. Nonetheless
from C to C' there has been a rotation of 90 degrees clockwise
proof:
Clockwise 90 degrees rotation law : (x,y) --> (y,-x) and it proves the change from C to C'
Therefor
all left to do is estimate the B point coordinates and implement the law of rotation
B(8,-7) Now implement a rotation of 90 degrees clockwise
we would get
B'(7,-8)
Hope that helps
