Given:
ABCD is a rectangle.
MD – perpendicular to the plane of the rectangle.
To find:
Distance from point M to BC.
Decision:
MD is perpendicular (ABC).
This means MD is perpendicular to any straight line that is in the plane (ABC).
Hence it follows that MD is perpendicular to BC.
Now let’s calculate the distance from point M to BC.
AB is perpendicular to BC.
Since ABCD is a rectangle, the distance from point M to BC will be equal to the length of segment AB.
Answer: AB.
