Q. 64.1( 59 Votes )
Construct a parallelogram ABCD in which AB=6.5cm, AC=3.4cm and the altitude AL from A is 2.5 cm. Draw the altitude from C and measure it.
STEP 1: At first draw a base line of 6.5 cm by scale.
STEP 2: Then draw a line perpendicular to AB from A with the help of protractor.
STEP 3: Then from A draw an arc of radius 2.5 cm on the perpendicular line. That intersecting point is L.
STEP 4: Then from L draw a perpendicular line with respect to AL.
STEP 5: Now from A draw an arc of radius 3.4 cm on the new line perpendicular to AL. That point is C.
STEP 6: From C draw an arc of radius 6.5 cm on the perpendicular line CL. That intersecting point is D.
STEP 7: Join AD and BC.
According to the problem, AL = 2.5 cm which is the altitude from point A. Similarly from point C altitude is CM which is of same length of AL = 2.5 cm.
