Question

Construct a parallelogram ABCD in which AB=6.5cm, AC=3.4cm, and the altitude AL from A is 2.5cm. Draw the altitude from C and measure it.

Answer 1

We know, AB=6.5cm, AC=3.4cm, AL=2.5cm

From the above figure the construction is not possible. So we have to find the altitude using from D.

Length of the perpendicular from A on DC= AL= 2.5cm (since the perpendicular length is the same on both side).

∴ The length of the perpendicular from D on AB=DM= 2.5cm.
