The circle and triangle are as shown. The options are:
A-B and C-B
E-F and E-D
E-D and C-D
A-F and E-F
C-B and C-D
By drawing radius lines from the center of the circle to the tangent points B, D, and F, we can divide the triangle into 3 kites. Therefore, only segments that are legs of the same kite are congruent. So the answer must be E-F and E-D, and C-B and C-D.
