In a rhombus ABCD, AC = 3 units and angle ABC = 120°. What is …
WebA=60 deg implies B = D =120 deg and C = 60 Draw an equilateral triangle ABD with 5 cm side length and its mirror image CBD to complete the rhombus. Robert Nichols Author has 5K answers and 11.8M answer views 5 y Related How do I construct rhombus with one side = 5cm? Begin by setting your compass to 5 cm. Then draw a segment AB that is 5 cm long. 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 WebSep 14, 2014 · The fours sides of a rhombus are of equal length. This also means that opposite angles of a rhombus have equal measure. The interior angles add up to 360 … shark euro pro steam mop s3101 manual
