#1   Concyclic points are not always coplanar.




#2   All sequences can be expressed with a general term.




#3   0! = sin 90




#4   The uniform cross-section of a cylinder is not always a circle.




#5   Cubes have nine planes of symmetry.




#6   nP(n-1) = n!




#7   The equation of a vertical line is y = a, where a is a constant.




#8   If two quadrilaterals share a common vertex, they are tangent polygons.




#9   If two coplanar triangles have one common side and their vertices are concyclic, then the angles at the non-overlapping vertices must be equal.




#10   A quadrilateral with a pair of equal opposite sides and a pair of parallel sides must be a parallelogram.




#11   If f(a) = f(b), then a = b, where a and b are constants.




#12   On a map, it only takes four colours to make sure each area's colour is distinct from that of its neighbours.




#13   If a point with the coordinates (a, b) is rotated about the origin 90 degrees clockwise, then the new point will be located at (b, -a).




#14   Let's say a cone is cut from a larger cone, leaving a frustum. By cubing the ratio of the cone's base radius to that of the frustum, we get the ratio between their volumes.




#15   Some cones have a curved surface area of pi * r * s, where s is the slant height; others do not.
