We have seen that a triangle has six parts-three sides and three angles. But to construct a triangle, you need to know only three parts. So we can construct a triangle using the SAS, ASA, SSS and RHS axioms.
Now, a question arises whether 4 measurements would be sufficient to draw a unique four sided closed figure namely, a quadrilateral. As, a Quadrilateral has eight parts, we need to know at least 5 parts to draw a Quadrilateral.
While constructing Quadrilaterals, we will find some can be constructed easily but some are not that easy to construct.
