Abcd is a rhombus. fill in the missing steps in the two column proof to explain why abc is congruent to cda.

1)Opposite sides of a rhombus are have the same length. 
2)Same thing as statement 1: Opposite sides of a rhombus have the same length.
3) The side AC is common to the two triangles ABC and CDA. 
4)The two angles ABC and CDA are congruent   by the SSS theorem of 
congruent triangles 

Ibelieve the answer would be 7, 13, 23
