Reflexive Property- A quantity is equal to itself ( think SHARED)

Partition-A whole angle,line segment,etc. is equal to the sum of its parts

Addition Postulate-Equals added to equals are congruent (GRAPS OR GAPS)

Subtraction Postulate-Equals subtracted from equals are equal (GPS)

Linear Pair-If 2 angles are congruent, then their supplements are congruent

Multiplication Postulate- Equals multiplied by equals are equal

Division Postulate-Equals divided by equals by non-zero equals are equal

*Halves of halves are equal*

A midpoint divides a segment into 2 segments that measure half of the original statement

Line Segment-The set of all points on the same line, that lie between 2 endpoints

Midpoint-Divides a line segment into 2 congruent segments

Bisector of a line segment- a line or line segment that intersects a line segment at its midpoint

Angle Bisector-A line, ray, or line segment that splits an angle into two congruent angles

Perpendicular Lines-Two lines or line segments that intersect to form right angles

Perpendicular Bisector-A line or line segment that intersects a line segment at its midpoint to create right angles

Linear pair-Two adjacent angles that form a straight line. SUPPLEMENTARY

Vertical Angles- 2 angles that are formed from intersecting lines and are congruent

Isosceles Triangle-contains 2 congruent sides and angles

Median-line segment drawn from any vertex of a triangle to the midpoint of the opposite side

Altitude-segment drawn from any vertex of a triangle perpendicular the line containing the opposite side
