Triangles have common side AC, and 2 adjacent to this side corresponding angles.
∠BAC=∠DCA, and
∠ACB=∠SAD.
So, triangles <span>ABC and ADC are congruent by ASA.</span>
Well, you can cancel out the b and e, so a/c = f/d.
Then you cancel out a on the left side of the equation by multiplying both sides by 1/a which then gives you c = f/ad.
