How many acute and obtuse angles does a Rhombus have?
One of the properties of a rhombus is that the opposite angles are equal. As a rhombus leans over more and more, two of the angles become more obtuse and the other two become more acute..
There are also 4 pairs of parallel lines in a rhombus. giving pairs of co-interior angles....
Similarly, as one angle becomes more obtuse, the other becomes small to maintain the sum of the co-interior angles at 180°.
