Step-by-step explanation:
A circumcenter is the point where the perpendicular bisectors of a triangle intersect.
This means
- BD = DC;
- BF = FA;
- AE = EC.
Since BC = 24 units, then BD = 12 units (half of BC).
Since FA = 8 units, AB = 16 units (twice FA).
Consider right triangle BGF. In this triangle, BF = 8 units (congruent to FA), BG = 13 units. By the Pythagorean theorem,
Triangles BFG and AFG are congruent right triangles, then BG = AG. In right triangle AGE, units,
units. By the Pythagorean theorem,
