Alex is constructing a square in which two of its vertices are points X and Y. He has already used his straightedge and compass to construct the lines and arcs shown.
What should Alex do for his next step?
A. Use a straightedge to draw a horizontal line that contains point Z.
B. Place the point of the compass on point X and draw any arc above it.
C. Use a straightedge to draw XZ¯¯¯¯¯ .
D. Place the point of the compass on point Y and draw an arc that intersects YZ¯¯¯¯¯ , using XY as the width of the opening of the compass.

Answer:
Step-by-step explanation
The standard equation of a circle centered at origin is
r = radius of the circle
The circle is passing through the point (0,5)
∴ radius
∴ The equation of the circle is
