Plot point Z (5, –6) on the Cartesian plane. Construct a right-angled triangle IZN and find Class 9

Question 1.

Plot point Z (5, –6) on the Cartesian plane. Construct a right-angled triangle IZN and find the lengths of the three sides. (Comment: Answers may differ from person to person.) Class 9

Solution:

IZ = 4 units, NZ = 3 units, IN = 5 units.

Question 2.

What would a system of coordinates be like if we did not have negative numbers? Would this system allow us to ; locate all the points on a 2-D plane? Class 9

Solution:

Without negative numbers, the coordinate ! system would have only the first quadrant.

This system would not allow us to locate all the points on 2D plane (the points below x-axis and the points to the left of y-axis).
