Question

ABCD is a rhombus angle is equal to angle C is equal to 60 degrees angle a b is equal to 60 degree find angle ADC

Answer 1

I WILL BE GLAD TO ASSIST YOU, LET'S START,

*A rhombus is not possible to be formed by this angle

Rhombus's all sides are equal and opposite angles are equal.
Total sum of angles of rhombus = 360° (Angle Sum Property)
In the given question,
∠A = 60°
∠B = 60°
∠C = 60°
And let ∠D = x
∴ ∠A +∠B +∠C + ∠D = 360°
⇒ 60° + 60° + 60° + x = 360°
⇒ 180° + x = 360°
⇒ x = 360° - 180°
⇒ x = 180°
Hence, ∠D = 180°
∴ Rhombus is not possible, because 180° formes a line.
