Question

For a king post truss to be constructed correctly, L must lie on the bisector of angle OJN. How can braces LK and LM be used to ensure that L is in the proper location?



LM and LK should be half the length of JO and JN.
LM and LK should be half the length of NO.
LM should be the perpendicular bisector of JO, and LK should be the perpendicular bisector of JN.
LM and LK should be congruent to JL.
