.
Make a sketch.
In the sketch, find all mentioned angles.
Then use the statement "C is in the middle".
It is VERY BAD way to formulate a MATH statement.
but I can interpret it as if the intersection point divides the corresponding segments in equal parts.
To make your final conclusion about congruency of triangles, use SAS-test of triangles congruency.
