Every rectangle is also a parallelogram. Viewing a rectangle as a parallelogram, we can choose a base and height for it, as for any parallelogram. In the case of a rectangle, what are other names for base and height?

write all of the equations of the lines that map the square onto itself

The size of a TV screen is stated in inches, a 45-inch TV, a 60-inch TV, etc. But a TV screen or a cell phone screen is a surface so its size should be measured in square inches rather than inches. It turns out that the advertised screen size is actually the length of the diagonal line of the screen. So a cell phone with a 6-inch screen may have a different screen area than another cell phone that also has a 6-inch screen. Find the area of the rectangles. Round answer to two decimal places.

a and b are two points in the third-dimenson. Show the equation that describes the set of points that are the same distance away from a and b.

a and b are two points in the third dimension. Write an equation that describes the set of points that are equidistant to a and b. Draw a picture of this set in the case where a = i and b = j.

A = {1,3, 5}, B = {2,3} Check ALL of the following Cartesian products to which the following elements belong:
