Troy starts to construct a triangle congruent to right isosceles triangle ABC. He begins by constructing a perpendicular through a point not on a line, as shown.



Use the drop-down menus to complete the additional steps needed to finish the congruent triangle construction.

Place the compass center at C and set the radius to the length of CB. Because
, he needs to set the compass radius only once.

Keeping the compass width the same, move the compass center to F and draw arcs to intersect segments
.

The points where the arcs intersect the segments are the
of the triangle. Construct segments to form the remaining sides of the triangle.
