WebABCD is a rhombus. So all of its sides are equal. Now, BC = DC ⇒ ∠BDC = ∠DBC = x (Angles opposite to equal sides are equal) Also, ∠BCD = 60° ∴ x + x + 60° = 180° ⇒ 2x = 120° ⇒ x = 60° i.e., ∠BCD = ∠BDC = ∠DBC = 60° So, ∆BCD is an equilateral triangle. ∴ BD = BC = a Also, OB = a /2 Now, in ∆OAB, we have: AB^2= OA^2 + OB^2 WebAll of the interior angles of the rhombus are degrees. Correct answer: Both of the remaining angles are degrees. Explanation: The four interior angles in any rhombus must have a sum of degrees. The opposite interior angles must be equivalent, and the adjacent angles have a sum of degrees.
