Kangaroo has four legs, including two forelegs and two hind legs. Hind legs of Kangaroo are Z-shaped. On the other hand, the forelegs of Kangaroo are very short and they usually use them for carrying food. Even the large Kangaroo use the forelegs for fighting but the hind legs of all Kangaroos are always more powerful and stronger. I am uploading the picture, and for more clarification view it.
They have four legs.
2 very strong back legs,+ 2 small front legs,+ 1 powerful tail= KANGAROO!
I say 2 but others say 4
