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 because there are four side. (n-2) (180)=Interior Angle; where n=number of sides. So if the opposite angles are equal then if ABC=64, ABD=ABC=64. WebBC = AB (side of a rhombus are equal to each other) 1 = 2 (angles opposite to equal sides of a triangle are equal) But 1 = 3 (alternate interior angles for parallel lines AB and CD) 2 = 3 So, AC bisects C. Also, 2 = 4 (alternate interior angles for lines BC and DA) 1 = 4 So, AC bisects A Similarly, we can prove that BD bisects B and D as well.
