In the figure YZ is parallel to MN, XY is parallel to LM and XZ is parallel to LN (X on MN, Y on LN, Z on LM). Then MY is:
Elementary MathematicsGeometry
- Athe median of triangle LMN
- Bthe angular bisector of angle LMN
- Cperpendicular to LN
- Dperpendicular bisector of LN
Explanation
The three parallels force X, Y, Z to be midpoints, so MY joins M to the midpoint of LN.
