Question

Chapter - introduction to graph.

Write the coordinates of the vertices of each of these figures

Answer 1

$\huge \text{REQUIRED \: ANSWER - }$

Since O is the origin, therefore its coordinates are (0, 0). Since A is at a distance of +2 units from the y-axis and at a distance of 0 units from the x-axis, therefore its x-coordinate is 2 and y-coordinate is 0.

Hence, the coordinates of A are (2, 0). Similarly, the coordinates of B, C, D, E, F, P, Q, R and S are (2, 6), (0, 6), (6, 6), (4, 3), (7, 4), (8, 7), (11, 9), (11, 5) and (8, 3) respectively.

--------------------------------------

• A - (2, 0)
• B - (2,6)
• C - (0, 6)
• D - (6, 6)
• E - (4, 3)
• F - (7, 4)
• P - (8, 7)
• Q - (11, 9)
• R - (11, 5)
• S - (8, 3)

Answer 2

Since O is the origin, therefore its coordinates are (0, 0). Since A is at a distance of +2 units from the y-axis and at a distance of 0 units from the x-axis, therefore its x-coordinate is 2 and y-coordinate is 0.

Hence, the coordinates of A are (2, 0). Similarly, the coordinates of B, C, D, E, F, P, Q, R and S are (2, 6), (0, 6), (6, 6), (4, 3), (7, 4), (8, 7), (11, 9), (11, 5) and (8, 3) respectively.

C - (0, 6)

D - (6, 6)

E - (4, 3)

F - (7, 4)

P - (8, 7)

Q - (11, 9)

R - (11, 5)

S - (8, 3)
