Need asap brainliest and 80 points
george is constructing the circumscribed circle for △rst. he has already used his compass to complete the part of the construction shown in the figure.
which construction could be his next step?
construct the line through points a and d and a second line through points b and c.
construct the line through points a and t and a second line through points b and s.
construct the line through points a and c and a second line through points b and d.
construct the line through points a and b and a second line through points c and d.

Construct the line through points A and B and a second line through points C and D.

Step-by-step explanation:

Construct the line through points A and B and a second line through points C and D.

This would be correct answer

Given is a triangle RST.  George has to construct a circumscribed circle for RST

We know that circumcentre of any triangle is the point of intersection of perpendicular bisectors of all sides.

Two sides are taken here RS and ST.  With radius equal to more than half of RS two arcs are constructed above and below RS with centre at R and S.

The intersection A and B if joined give the perpendicular bisector of RS, Same thing for CD. THe intersecting point of AB and CD determine the circumcentre.(say S1)  Wtih centre at S1 radius = S1R, the circle can be drawn
