The next step of Ricardo is to Construct the perpendicular bisector of YZ.
Given,
Ricardo is constructing the circumscribed circle for [tex]\Delta XYZ[/tex] As shown in figure.
We have to find the next step in the construction of circumscribed circle for [tex]\Delta XYZ[/tex].
How to draw the circumscribed circle?
first we find the Circumcenter of the triangle.
We know that the point at which the perpendicular bisector of any two sides of triangle intersect each other will be the Circumcenter of that triangle.
Since in the construction steps of Ricardo he only draws the perpendicular bisector of side XY.
So his next must be to draw the perpendicular bisector of other sides.
Since the options contain only the perpendicular bisector of side YZ. so this step will be his next step.
Hence the correct option is B. Construct the perpendicular bisector of YZ.
