Construct a quadrilateral ABCD in which AB = 3.8 cm, BC = 3.0 cm, AD = 2.3 cm, AC = 4.5 cm and BD= 3.8 cm.
Steps of construction:
Step I: Draw AC = 6 cm.
Step II: With A as the center and radius 3.8 cm, draw an arc.
Step III: With C as the center and radius 3.0 cm, draw an arc to intersect the arc drawn in Step II at B.
Step IV: With B as the center and radius 3.8 cm, draw an arc on the other side of AC.
Step V: With A as the center and radius 2.3 cm, draw an arc to intersect the arc drawn in Step IV at D.
Step VI: Join BA, DA, BC and CD to obtain the required quadrilateral.
Construct a quadrilateral ABCD in which BC = 7.5 cm, AC = AD = 6 cm, CD = 5 cm and BD = 10 cm.
Steps of construction:
Step I: Draw AC = 6 cm.
Step II: With A as the center and radius 6 cm, draw an arc.
Step III: With C as the center and radius 5 cm, draw an arc to intersect the arc drawn in Step II at D.
Step IV: With D as the center and radius 10 cm, draw an arc on the other side of the line segment AC.
Step V: With C as the center and radius 7.5 cm, draw an arc to intersect the arc drawn in Step IV at B.
Step VI: Join BA, DA, BC and CD to obtain the required quadrilateral.
Construct a quadrilateral ABCD, when AB = 3 cm, CD = 3 cm, DA = 7.5 cm, AC = 8 cm and BD = 4 cm.
If we consider a triangle ABD from the given data, then
AB = 3 cm
BD = 4 cm
AD = 7.5 cm
AB + BD = 3 + 4 = 7 cm
However, we know that the sum of the lengths of two sides of a triangle is always greater than the third side.
Therefore, construction is not possible from the given data.
Construct a quadrilateral ABCD given AD = 3.5 cm, BC = 2.5 cm, CD = 4.1 cm, AC = 7.3 cm and BD = 3.2 cm.
Steps of construction:
Step I: Draw CD = 4.1 cm.
Step II: With C as the center and radius 7.3 cm, draw an arc.
Step III: With D as the center and radius 3.5 cm, draw an arc to intersect the arc drawn in Step II at A.
Step IV: With D as the center and radius 3.2 cm, draw an arc on the other side of AC.
Step V: With C as the center and radius 2.5 cm, draw an arc to intersect the arc drawn in Step IV at B.
Step VI: Join BA, DA, BC and BD and AC to obtain the required quadrilateral.
