You will use GeoGebra to explore the relationship between the slopes of perpendicular lines. Reopen slope of parallel and perpendicular lines, and complete each step below. Question 1
Create a line that is perpendicular to and passes through point C. You can use the tools available in GeoGebra to create perpendicular lines for this construction. Display the measurement of the angle of intersection between the two lines. Take a screenshot of your results, and paste it below.

1- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis.2- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in the first question?
