All I'm asking is for someone help me prove these calculations incorrect.

The figure below shows a circle with two chords JM and KL intersecting at point S.
Grace took the measurements of the line segments and wrote them down as shown. Segment KS is 1.8 cm, segment SM is 2.5 cm, segment JS is 4.5 cm, and segment SL is 1.2 cm. Describe the method you use to prove that Grace took incorrect measurements. Use geometric theorems to write a two-column proof.
