Practice Point in Math
Use these practice problems to test your method after reviewing the concept explanation and worked examples.
Quick Recap
An exact location in space with no size, length, or width—zero dimensions; named with a capital letter.
The tip of a pencil or a dot on a map. Position only, no width or length.
Example 1
easyPlot the point (3, 2) on a coordinate grid and describe its location.
Example 2
mediumPoints A(1,1), B(4,1), and C(4,5) are three corners of a rectangle. What are the coordinates of the fourth corner D?
Example 3
easyWhat are the coordinates of the origin on a standard coordinate grid?
Example 4
hardIn 3D space, describe the point (2, -3, 5). How does adding a third coordinate change what a point represents compared to 2D?
