How many parallelograms will be formed if 9 parallel horizontal lines intersect 8 parallel vertical lines?
Question
Solution 1
To find the number of parallelograms formed by the intersection of parallel lines, we use the formula:
nC2 * mC2
where nC2 is the number of combinations of n items taken 2 at a time (in this case, the horizontal lines), and mC2 is the number of combinations of m items taken 2 at a time (in this ca Knowee AI StudyGPT is a powerful AI-powered study tool designed to help you to solve study prob
