The Latin root word ped and its Greek counterpart pod both mean “foot.” These roots are the word origin of many English vocabulary words, including pedal centipede, podium, and podiatrist. Humans, for instance, are bipedal because they walk on two “feet,” whereas a tripod is a stand for a camera that has three “feet.”
The root word in Tripod would be Tri.

Tri 
meaning 3, such as tricycle.

Hope this helps.!
