Plot the points A(4,0),B(−1,4) and C(−1,−4) on a graph paper. Now, observe the figure and state the line of symmetry if it shows.
Use graph paper for this question. Take 1 cm = 1 unit on both axes.
i) Plot the points A (–2, 0), B (4, 0) and C (1, 4) on the graph.
ii) Plot D (–2, 4) and E (4, 4). Assign special name to quadrilateral ABED.
iii) Draw lines of symmetry of quadrilateral ABED, and DABC.
iv) Write the equation of lines of symmetry.
Use graph paper for this question.
A(0, 3), B(3, -2) & O(0, 0) are the vertices ∆ ABO.
Plot the ∆ on a graph taking 2 cm = 1 unit on both axes.
Plot point D, which is the reflection of B in the Y axis.
a) Give geometrical name to the figure ABOD.
b) Write the equation of line of symmetry of figure ABOD.
