Odd plant with a triangle shape on its leaves

Hey All

I found this plant in my garden. It has a nice pattern of a triangle displayed on its leaves. It is also sending out runners. I was just wondering if anyone could ID it?

 

It looks like Trifolium sp.
Common name Clover.

Not sure which ones you get in South Africa.

Thanks Googled for some images and it's definitely one :D Usually the clovers here are quite bland without any sort of pattern. I see it's mentioned as a weed
