	The angle at the vertex of an isosceles triangle		2015-11-25
		Karan pose la question : I have been given an isosceles triangle. the Top angle is what i have to find out and the two sides adjacent to it are both 4.9 cm. i have been told that the area of the triangle is 4 cm^2. i have no idea how to work this out, any ideas? Penny Nom lui répond.
	The maximum distance from the vertex of a triangle		2012-05-02
		David pose la question : There are three towns A,B,and C, equi-distant apart. A car is 3 miles from town A, and 4 miles from town B. (ie, somehwere outside of the triangle which the three towns form) What is the maximum distance that the car can be from town A? This was asked as quiz question in my local pub last Sunday. The answer is 7. How do I prove it? Best regards. David in Denton. Robert Dawson and Chris Fisher lui répond.

	The third vertex of a triangle		2010-09-23
		nikos pose la question : Hi, I would really appreciate any help in this: "Suppose you have a triangle (any triangle, no hypotheses allowed), let's call it ABC. You know the coordinates of the two vertexes, A(x1,y1), B(x2,y2) and the area of the triagnle, let's call it D. Can you find the third vertex of this triangle based on these facts?" Thanks a lot! Harley Weston lui répond.
	The "vertex" of a cone		2010-04-27
		Tom pose la question : By definition a vertex is a point where three edges meet in a 3 dimensional object. My ten year old son argues that the point at the top of a cone is not a vertex since it does not fit the definition. He got the answer wrong on a test recently but insists that he is right. I need a mathematician to answer this for him. Robert Dawson and Chris Fisher lui répond.
	The fourth vertex of a rectangle		2009-11-11
		Ellena pose la question : The points A(2,-1), B(5,-3), and C(7,0) are the three vertices of a rectangle. Determine he coordinates of the fourth vertex. Penny Nom lui répond.

	A triangular pyramid		2009-02-26
		Craig pose la question : Can you help with this question: Write the names of the faces and the number of each kind of face on a triangular pyramid? Penny Nom 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.

		miriam pose la question : how many verticies does a cone have Penny Nom lui répond.
	Sides and vertices		2007-11-17
		derek pose la question : What is the correct name for a 2D geometric shape that would look like one slice from a round pizza and how may sides and vertices would it have? I believe you would say it has one vertex and two sides with the curved boundary not resulting in vertices or a side. Your help is much appreciated. Chris Fisher and Walter Whitelty lui répond.
	Vertices		2007-09-18
		Richard pose la question : Please help. Do not understand vertices, as in how many in a cone, hemisphere, etc. Harley Weston lui répond.

	Is the point on a cone called a vertex?		2007-05-09
		Felicia pose la question : Does a cone have a vertice? My teacher says that a vertice can only be made if two or more edges join up at an angle, so what do you call a point on a cone? Walter Whiteley lui répond.
	Octagonal Stop Sign		2006-10-23
		Phil pose la question : My colleagues and I are in a discussion about how many true "sides" an octagonal stop sign has. I say that it has 10 true sides because of the front back sides of a stop sign (3D octagon). Is this correct terminology or should the front and back "sides" be referred to as faces -- equaling 2? Paul Betts, Steve La Rocque and Harley Weston lui répond.
	Quadratic Equations & Given Roots		2005-11-11
		Lindsey pose la question : I need to find the quadratic equation in the form: f(x)=a(x2 - (-b/a)x + (c/a)) The vertex is (1, -7), the roots are (4, ?) I need to find the other root but I don't know where to begin. My answer key says the other root is (-2). How is this possible? Penny Nom lui répond.
