Construction of Quadrilaterals Quadrilateral has 4 sides 4 angles 2 diagonals To draw quadrilateral, we need any 5 measurements (not 4) 4 sides & 1 diagonal 3 sides & 2 diagonals Two adjacent sides and three angles 3 sides and two included angles When other special properties are known. (Like square’s side) Let’s look at them one by one Why does Quadrilateral need 5 measurements? Why not 4? We know that to draw a triangle, we need 3 measurements – 3 sides, 2 angle 1 side etc. So, for Quadrilateral, we should need 4 measurements Eg: 4 sides Let’s draw a quadrilateral with 4 sides as 5 cm, 4 cm, 5 cm, 4 cm To construct it, let’s assume we have 4 sticks of sizes - 5 cm, 4 cm, 5 cm, 4 cm Let’s connect the lines to make a quadrilateral We can join the lines like Or like Thus, we get different quadrilaterals when we have 4 measurements. So, to get one quadrilateral, we need 5 measurements Let’s learn them one by one
