Question

The figure below shows rhombus ABCD.


The paragraph proof with missing statement proves that the opposite interior angles of the rhombus are congruent

Which statement can be used to fill in the blank space?

The figure is a rhombus which is given. The definition of a rhombus guarantees that Line segment AB and Line segment CD are parallel and that Line segment AD and Line segment BC are parallel. ∡1 + ∡2 = 180 and ∡2 + ∡3 = 180 because they are same side interior angles of two parallel lines cut by a transversal. By the transitive property of equality, _________________________

Answer 1

∡1 + ∡2 = ∡2 + ∡3

∡1 = ∡3

∡1 + ∡2 = ∡3 + ∡4

∡1 + ∡2 = 180 and ∡2 + ∡3 = 180
