In geometry the term construction is mainly used for drawing different geometrical shapes like circle, triangle, square, rectangle, rhombus, parallelogram, etcaccurately using geometrical equipments including a ruler, pencil, compass and protractor. Each geometric shapes have their own construction steps and properties.
Here are the simple construction steps for drawing parallelogram ABCD.
Given: AB = 8 cm, BC = 9 cm and AC = 10 cm.
Step-1: With the help of a ruler and pencil, draw a straight line measuring AB =8 cm.
Step-2: Keeping C as midpoint, draw an arc BC = 9 cm.
Step-3: Now keeping A as center, draw an arc AC = 10 cm cutting the preceding arc at C.
Step-4: Connect AC and BC.
Step-5: Keeping C as middle and radius equal to 5 cm, draw an arc.
Step-6: With C as middle and radius equal to 10 cm, draw an arc cutting the previous arc at B.
Step-7: Now connect AD and CD.
Step-8:Here is the parallelogram ABCD.
