Formula used : By the virtue of similarity, if any two angles of the triangles are congruent, the third one will also be congruent
Proof : In triangles JOG and MHG,
is common angle
(Rhombus)
Thus, using virtue of similarity, we know that triangles JOG ang MHG are similar triangles.
Now,
is common angle
Thus, we know that
Hence, by virtue of congruency,
