Exercise 4.2 - Chapter 4 - Practical Geometry - NCERT Maths Class 8th

We shall learn how to construct a unique quadrilateral given the following measurements:
• When four sides and one diagonal are given.
• When two diagonals and three sides are given.
• When two adjacent sides and three angles are given.
• When three sides and two included angles are given.
• When other special properties are known.
