is a rhombus such that Then is
The explanation for the correct option:
Option (C):
Solution:
According to the given details, is a rhombus
(opposite sides of the rhombus are parallel)
[Alternate interior angles]
We know that the diagonals of a rhombus are perpendicular to each other
So,
We also know that the sum of interior angles of a triangle is
Sum of all angles of a triangle
Hence,
