Answer: Angle Addition Postulate

Step-by-step explanation:

  • According to the angle addition postulate, the measure of an angle formed by two angles side by side is the sum of the measures of the two angles.
  • It is used to evaluate the measure of an angle formed by two or more angles .

In the given picture, we have ∠MRO and ∠MRS on line SRO.

So, ∠SRO = ∠MRO +∠MRS  [By angle addition postulate]

So the postulate that justify the statement " ∠SRO = ∠MRO +∠MRS" is Angle Addition Postulate.
