Question

Take a graph paper and mark the points A(2,0), B(2,8) and C(S,4) on it. Taking AB as the line of symmetry, obtain and write the co-ordinates of point D. Complete the quadrilateral ABCD and give its geometrical name. 

Answer 1

Steps of oonstruction: 

(i) Plot the points A, Band Casper given data. 

(ii) Point D symmetrical about AB is a point with vertices x= -1 and y = 4 1. e. 3 units left of line AB. 

(iii) Plot D( -1,4) 

(iv) Join BC, AB, BD 

The figure is an arrow.
