Determine whether angle-angle-angle (AAA) is a valid means for establishing triangle congruence. If it is a valid criterion, exp
lain 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.

Answer: 30, 60, 90 triangle ==> Option 3
Step-by-step explanation:
Lets say Angle A is the angle opposing the line of a triangle that has the length of 6. Lets say Angle B is the angle opposing the line of the same triangle that has the length of .
sin A=6/12=1/2
sin A=30 degrees.
sin B==
sin B=60 degrees.
Hence, triangle is 30, 60, 90 triangle ==> Option 3
