Given : equilateral quadrilateral
and half of one angle = 60°
To Find : the measurement of angle Y.
Solution:
equilateral quadrilateral means Rhombus
Diagonal of rhombus bisect each other perpendicularly
Hence angle at intersection = 90°
90° + 30° + y = 180° ( sum of angles of a triangle )
=> y = 60°
the measurement of angle Y is 60°
