In this worksheet, we will learn about plotting points in quadrants 1 - 4.
In quadrant 1, the numbers are at the top right section of the graph with positive x and y-coordinates.
In quadrant 2, the numbers are at the top left section of the graph with negative x-coordinates and positive y-coordinates.
In quadrant 3, the numbers are in the bottom left section of the graph, with negative x and y-coordinates.
In quadrant 4, the numbers are in the bottom right section of the graph, with positive x-coordinates and negative y-coordinates.
Remember that the x-coordinate comes before the y-coordinate.
The coordinates of the corners of the shape above are (1, 1), (4, 1), (5, 2), (3, 5).
When we reflect a shape, it is mirrored across the x- or y-axis.
In the example below, the semi-circle (shape A) has been reflected across the y-axis to become shape B.
Notice how it is an equal distance from the y-axis on both sides.
