Show that each sequence below diverges. Determine, with proof, if it diverges to infinity/minus infinity or not. (a) {an} with an = n 2 − n. (b) {bn} with bn = 1 if n is odd and bn = −5 if n is even.

Determine whether angle-angle-angle (aaa) is a valid means for establishing triangle congruence. if it is a valid criterion, explain why. if it is not valid, use geogebra to create a counterexample demonstrating that it doesn’t work and give an explanation. if you construct a counterexample, take a screenshot of your work, save it, and insert the image in the space below.
