Theorems for module 14-15 Math test
Rectangle
4right angles/ diagonals are congruent
Angle bisector
A bisector forms 2 equal angles
Side angle relation ship
Larger angle is opposite side of the larger angle
Quadrilateral= parallelogram
Opposite sides are congruent/opposite angles are congruent/ diagonals bisect each other
Triangle inequality theorem
The sum of two sides must be greater than the third
Rhombus
Equal side length/ diagonals are perpendicular/ a diagonal bisects a pair of opposite angles
Converse of angle bisector
If a line makes two sides equidistant from each other, than the line is a bisector
Polygon angles
(N-2)180
Incenter
Angle bisect of a triangle intersect at a point that is equidistant from the sides
Triangular sum theorem
Sum of angles =180
