The mid points of AB and AC of a △ABC are X and Y, respectively. If BC+XY=18 units, then the value of BC-XY is:
Given:
The midpoints of AB and AC are X and Y, respectively.
BC + XY = 18 units.
Formula Used:
The line segment joining the midpoints of two sides of a triangle is parallel to the third side and half its length.
Thus, XY =
Solution:
Finally, BC - XY = 12 - 6 = 6 units.
