In this topic, students learn to draw a quadrilateral when measurements of any three sides and both diagonals are given.

About NCERT Class 8 Maths Chapter 4: Practical Geometry

In Class 7, students have learned how to draw triangles. Moreover, students learn that they just require three measurements of sides or angles to draw a unique triangle. However, similarly to a triangle, we can’t draw a unique four-sided closed figure, namely, a quadrilateral with four measurements.

For example, if we take two pairs of sticks of equal length, we can make a rectangle. However, what happens if we push along the breadth of the rectangle? The rectangle becomes a parallelogram with the same measurements. Thus, four measurements are not sufficient to draw a unique quadrilateral.

However, if we take five measurements, then it is possible. How? Take the same two pairs of sticks of equal length and one more stick k of length equal to the diagonal. Now, push the breadth. We can see that the shape is not changing without making the figure open. Hence, the fifth stick made the rectangle fixed uniquely.
