Page1/1            A cyclic quadrilateral 2014-03-28 From Carly:Suppose ABCD is a cyclic quadrilateral, i.e A, B, C, and D are the points on a circle, given in order going around the circle. Show that if we join each of A, B, C, and D to the orthocentre of the triangle formed by the other three, then the resulting line segments all intersect in a common midpoint. Thank you.Answered by Chris Fisher.     The circumcentre and orthocentre of a triangle 2012-04-25 From Nazrul:The circumcentre and orthocentre of a triangle is given. A point on a side of the triangle given. A vertex of the triangle on the circumcircle is also given. How can I draw the triangle? Please Help me. Thank you for answering my previous questions.Answered by Chris Fisher.     The circumcentre, centroid and orthocentre of a triangle 2012-04-24 From Nazrul:The circumcentre, centroid and orthocentre of a triangle is given. The distance between circumcentre and orthocentre is also given. How can I draw the circle? Please Help me.Answered by Chris Fisher.     The orthcentre and the circumcentre 2007-04-05 From Ruby:I have tried to do this question so many times, could you please, please, please show me how to do it. I just can't get the answer: What is the (i)Circumcentre and (ii)Orthocentre of the triangle with vertices a(-2,2) b(2,-6) c(5,3)? It would be so great if you could show me how to do this. Thanks in advance, Ruby.Answered by Penny Nom.     The orthocentre 2002-10-17 From Elsie: Find the orthocentre of the triangle with vertices at A(-3,4), B(10, -3) and C(3,-2). Find the distance of point X(3,8) from the line that passes through Y(-2, -2) and Z (3, -2). Answered by Chris Fisher.
