Use the diagram to answer the question.

Which of the following statements is true?
(1 point)

m∠LSO + m∠MSO = 180°

∠LSMcongruent ∠NSM

m∠LSM + m∠SML + m∠MLS = 360°

m∠NSO + m∠OSL + m∠LSM + m∠MSN = 360°

The correct statement is:

m∠NSO + m∠OSL + m∠LSM + m∠MSN = 360°

Based on the diagram, the true statement is:

m∠NSO + m∠OSL + m∠LSM + m∠MSN = 360°
