1. any equation that can be written in standard form
2. triangle measure
3. a statement that needs no proof
5. if a point is on the I bisect of a segment then it is equidistant from the end points of the segment
6. if two sides and the included angle of one triangle are congruent to two sides and the included angle of a second triangle then the triangles are congruent
