Is quadrilateral ABCD a rhombus?

1) AC is perpendicular to BD
2) AB+CD = BC+AD

Could someone please explain with a diagram along with any useful properties of rhombus(if any to solve these kind of problems)

Thanks!

Both kite and rhombus have the diagonals perpendicular to each other and the sum of the opposite sides equal to each other. So, ABCD can be a kite or a rhombus. Look at the diagram below:
