| Two objects are said to be congruent if they have | the same size and shape |
| The midpoint of a segment is the point that | divides the segment into two congruent segments. |
| If M is the midpoint of XY , then | XM = MY and XM = ½ XY and MY = ½ XY |
| A bisector of a segment is a line, segment, ray or plane that | intersects the segment at its midpoint |
| A bisector of an angle is a ray or line that | divides the angle into two congruent angles. |
| If EC bisects /_ BED, then | m /_ BEC = m /_ CED and m /_ BEC = ½ m /_ BED |
| If RS bisects /_ TRU, then | m /_ SRU = ½ m /_ TRU |
| The sum of the parts equals | the whole |
| If A is the midpoint of the line XYand XA = 4n - 6 and AY = 26 then | 4n - 6 = 26 |
