Geometry on hybrid bikes tends to be very close to that period's mountainbike geometry, usually something like 71-degrees headtube angle and 73-degrees seat tube angle.

Tourers often have a steeper head tube angle like 72-73 degrees, and the tourers tend to also have a slacker seat tube angle, 72-73 degrees.

Hybrid bikes, mountainbikes and cyclocross bikes all also have shorter chainstays than touring bikes, to give better rear tire traction while climbing off road. Slightly longer top tubes than on a touring frame are also somewhat typical.

I'm sort of waiting for a fad of interest in these vintage 700c hybrids. They do it all. My early-90's Performance Parabola "road hybrid" uses the same off-road frame tubing and geometry as a typical hybrid, but came with huge dual-pivot sidepull brakes and road-style handlebars. I've used it for everything from road riding to mountainbiking to cyclocross racing.
