Options:
a. It must be acute.
b. It must be a right angle.
c. It must be equal to Angle MRH.
d. It must be equal to Angle RMS.
Answer:
b. It must be a right angle.
Step-by-step explanation:
The figure attached shows the rhombus RHOM with RO and HM as diagonals and are the angle bisectors of the vertex angles.
Let S be the point where the diagonals RO and HM intersects each other.
ΔHOM, ΔMHR, ΔRHO, ΔOMR are four isosceles triangles in the given rhombus.
Since, Diagonals of a rhombus bisect each other at right angle.
Therefore, we have ∠MSR= 90°
That is, ∠MSR is a right angle.
