A polygon is a many sided 2-dimensional figure, and thus could never be "solid"
Alternatively, it could be "one face that is a polygon". In that case the solid could be like a pyramid that morphs into a cone or a part-sphere. The base would be the one polygon, the other face would not.
What else can I help you with?
What solid figure has one polygon face and triangles with common vertex?
a pyramid
What is a solid figure with one face that's a polygon and 3 faces that are triangles with a common vertex?
Pyramid
What solid figure has one polygon base?
a pyramid
Solid figure with one polygon base and triagular faces?
Such a figure is a pyramid.
Solid figure with one polygon base and triangular faces?
A polygonal pyramid.
A planar figure that is one side of a solid figure?
It is called a face.
What is a plane figure that serves as one side of a solid figure?
a face.
What is the solid figure for one circular face?
cone
What solid figure that has one circular face?
The answer is a cone
A solid figure with one polygon base and triangular faces?
a polygonal prism or a polygond
What is a solid figure with one face that is a polygon and three or more faces that are triangles with a common vertex?
A pyramid is a solid figure with one face that is a polygon and three or more faces that are triangles with a common vertex. Yeah, pg. 114 in the math workbook is a little hard, and the guy who answered this before me thought it was funny to improve the answer by saying the answer was 45. That's just not mature. I don't get it. Anyway, I hope you finish your homework at this rate.
What solid figure has only one face?
The sphere.
