1. Signal flares were launched from two different boats. The red flare followed the function f(x) = -(x - 15)2 + 175 and the green flare followed the function f(x) = -x(x - 25), where x was the horizontal distance in meters and f(x) was the height in meters. Which flare went the highest in the air? Provide
mathematical evidence to justify your answer.

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.
