${ \underline{ \sf{Required \: Answer :}}}$

• The triangle formed by the points (0,0), (3,0) and (0,4) is right angled triangle [As we can see in the attachment].

• To locate the position of an object or a point in a plane, we require two perpendicular lines. One of them is horizontal, and the other is vertical.

• The horizontal line X'X is called the x - axis.

• The vertical line Y'Y is called the y - axis.

• The plane is called the Cartesian, or coordinate plane and the lines are called the coordinate axes.

• The point where X'X and Y'Y cross is called the origin, and is denoted by O.

• Since the positive number live on the directions OX and OY, OX and OY are called the positive directions of the x - axis and the y - axis, respectively.

• Similarly, OX' and OY' are called the negative directions of the x - axis and the y - axis, respectively.
