Need answer fast. Find the coordinates of the vertices of the figure after a rotation of 180°.
1 answer:
Answer:
C. A'(3,4), B'(-1,3), C'(-1,-1)
Step by step answer:
The coordinates of the vertices are A(-3,-4), B (1,-3), C(1,1).
We have the formula for the rotating a shape at an angle of 180° which shows that you are reflecting the shape twice.
(x, y) -> (-x, -y)
So, the coordinates will be,
A(-3,-4) = A'(3,4)
B (1,-3) = B'(-1,3)
C(1,1) = C'(-1,-1)
Thank you.

Remember, for 
the x value of the vertex is 
so
given
x value of vertex is -5
and
multiply both sides by a
5=-5a
divvide both sides by -5
-1=a
a=-1
comlete the square
remember if we do
(h,k) is the vertex
I know, we can subsitute the known values of te vertex
-5 for h and 20 for k then expand
a=-1
c=-5
