Welcome to the page for the project that has high school students all over the country doing flips.  The presentation includes images of past projects to give you some inspiration, and the Flippin' Pics Zip Pack contains PNG images of all the diagrams from the Easy, Medium, and Hard sections as well as a generic image of two lines cut by a transversal with numbered angles.

Geometry 4(A) distinguish between undefined terms, definitions, postulates, conjectures, and theorems

Geometry 5(A) investigate patterns to make conjectures about geometric relationships, including angles formed by parallel lines cut by a transversal, criteria required for triangle congruence, special segments of triangles, diagonals of quadrilaterals, interior and exterior angles of polygons, and special segments and angles of circles choosing from a variety of tools 

Geometry 6(A) verify theorems about angles formed by the intersection of lines and line segments, including vertical angles, and angles formed by parallel lines cut by a transversal and prove equidistance between the endpoints of a segment and points on its perpendicular bisector and apply these relationships to solve problems
