Question

what type of machine is a seesaw? complex machine compound machine simple machine mechanical machine

Explanation:

A seesaw is a lever. Levers are one of the six simple machines. A simple machine has few or no moving parts and makes work easier. A complex machine (also known as a compound machine) is made up of two or more simple machines. Since a seesaw is just a lever (a simple machine), it is not a complex or compound machine. The term "mechanical machine" is too broad.

Answer:

simple machine
