Question

if a perpendicular drawn from an obtuse angle vertex of a rhombus to the opposite side bisects the side , all angkes of the rhombus are​

Answer 1

Step-by-step explanation:

Let the acute angle be A and obtuse angle be B. Rhombus ABCD, and angle A = angle C = acute angles. The perpendicular from B to AD be BE. Now in ÎABE, AE = ED = AB/2 = AD/2 cos A = AE/AB = 1/2 angle A = 600 = angle C angle B = angle D = (360 - 2x60)/2 = 1200.Read more on Sarthaks.com - https://www.sarthaks.com/10143/perpendicular-drawn-obtuse-angled-vertex-rhombus-opposite-bisects-find-angles-rhombus
