Solution

Perpendicular dropped on the base of a parallelogram from the opposite vertex is known as the corresponding height/altitude of the base.

Explanation:

In a parallelogram, the altitude (also called the height) is the perpendicular distance between a side (called the base) and the opposite side (or the line containing the opposite side).

  • It is drawn from a vertex to the line containing the opposite side.

  • This perpendicular segment is the altitude corresponding to the base.

Example:

In a parallelogram ABCD:

  • If AB is the base, then the perpendicular drawn from C to AB (or its extension) is the altitude corresponding to AB.
