Will give brainliest to first lots of points*** any would be appreciated. if you could even answer one of the problems i would be grateful!

B) RH = UM = HM = RU   Reason: Since they form a rhombus, its sides are of equal length.
c) RUBM is a rhombus Reason: Given
d) Reason: RUBM is identified as a rhombus. Thus, its sides are of equal length.
e) RUMH and  RUBM are rhombus which have similar dimensions. Each sides of any rhombus is equal in length and since both are of similar dimensions, then, all of their sides lengths are equal with each other.
f) Rhombus have opposite sides that are parallel and its opposite angles are equal. Rhombus is also called a parallelogram.
