	The faces of a triangle		2014-03-24
		Westun pose la question : Your answer says that a triangle has 0 faces but isn't the part of the shape you see the face!? Because i am having trouble with that so could you help me! thanks! :) Penny Nom lui répond.

	Vertices and sides of a polygon		2011-03-04
		RINA pose la question : My questions is : would a vertices and sides of a polygon be the same number.  For example, a octagon it has 8 points and 8 sides. Am i correct? Robert Dawson lui répond.
	A triangular pyramid		2010-01-05
		ally pose la question : how many vertices, edges, faces in a triangular pyramid? Robert Dawson lui répond.
	Vertices, edges and faces		2009-02-19
		Deb pose la question : I have been reading the responses you have to whether or not a cone and cylinder have edges, and whether a cone has a vertex. I have also found differing answers in different books and websites. Your idea that it depends why we want to call it a vertex or edge is interesting but does not help the students next year when they have a different teacher who tells them that whatever decision I make is wrong! It also doesn't help them when they do the provincial testing. Does anyone know if EQAO considers them vertices or edges? I want to know because textbooks and provincial tests often ask the students to count the number of faces, edges, and vertices or to describe a solid by using these, or to identify a solid that they have described. We need to have consistency in what we are teaching! Chris Fisher lui répond.

	What constitutes a face for a geometric solid?		2007-02-14
		Erica pose la question : What constitutes a face for a geometric solid? We have been getting conflicting answers from different textbooks. Some teachers are saying that cylinders and cones do not have faces. I'm thinking that cylinders have 2 and cones have 1. Please enlighten me. Thanks! Walter Whiteley lui répond.
	A cylinder has how many flat surfaces, vertices, and edges?		2007-01-09

	Intersection of perpendicular cylindrical surfaces		2001-07-31
		Charlie pose la question : Please consider two right circular cylinders, perpendicular one to the other, and of unlike radii in a 3 dimensional Cartesian space with mutually perpendicular x,y,z axes. If one cylinder is centered on the y axis with radius ra, and the other on the z axis with radius rb, then the expression for the first surface would be x2 + z2 = ra2, y = any number. Likewise, the second cylinder's surface would be x2 + y2 = rb2, z = any number. It is my intent to define the curve at the intersection of these two cylindrical surfaces. From sketching the conditions it appears that this intersection resembles an ellipse folded about its minor axis. Chris Fisher lui répond.
