Based on the figure RHOM being a rhombus and the angles that are formed, a true statement on Angle MSR is that It must be a right angle.
<h3>How is Angle MSR a right angle?</h3>
Lines RO and HM are drawn as diagonals and so will intercept at point S and divide the rhombus into 4 isosceles triangles.
With angle MSR starting from one end and going to the center and then to another end, it forms a right angle at point S as shown attached.
