True or False:  You use a regular triangle to tile a floor.  (Explain your answer)

True - six triangles will connect at one vertex with no gaps.  The interior angle of each regular triangle is 60 degrees.  6 interior angles at 60 degrees each totals 360 degrees.

I'm thinking of a regular quadrilateral. What do we call this shape?

Square

True or False:  You can tile a floor using regular pentagons.  (Explain your answer)

False - The interior angle of each regular pentagon is 108 degrees.  There is no combination of those angles that will add up to 360 degrees, therefore there will be gaps in the flooring.
