Answer:
Step-by-step explanation:
The <em>correct answer</em> is:
Use the circumcenter to determine the center of the circle
.
Explanation:
The steps James has completed have constructed the perpendicular bisectors of two sides of the triangle, DE and EF. The point where the perpendicular bisectors of the sides of a triangle meet is the circumcenter of the triangle. This is also the center of the circumcircle, or circumscribed circle.
We need to extend these bisectors so that they intersect. We then set our compass on this point and set the width from this center to any vertex of the triangle. This will be the radius of the triangle; we draw the circle and are finished.

Answer:
Step-by-step explanation:
For this exercise it is important to remember that a Right triangle is a triangle that has an angle that measures 90 degrees.
According to the Altitude Rule, given a Right triangle, if you draw an altitude from the vertex of the angle that measures 90 degrees (The right angle) to the hypotenuse, the measure of that altitude is the geometric mean between the measures of the two segments of the hypotenuse.
In this case, you can identify that the altitude that goes from the vertex of the right angle () to the hypotenuse of the triangle, is:
Then, based on the Altitude Rule, you can set up the following proportion:
According to the Leg Rule, each leg is the mean proportional between the hypotenuse and the portion of the hypotenuse that is located directly below that leg of the triangle.
Knowing this, you can set up the following proportions:
