Check the selectbox that says [b]Show / hide AAA[/b]. Triangles ABC and DEF have three sets of congruent angles. You can use sliders to adjust two of the angles. Use points B and E to adjust the triangles themselves. [br]1. Are ABC and DEF always congruent?[br]2. Is AAA a way to prove that triangles are congruent? Why or why not?[br]3. Make AB = 3 and DE = 6. Is there a relationship between the other sides as well?[br][br]Uncheck the selectbox that says Show / hide AAA. Check the selectbox that says Show / hide AAS. Triangles GHI and MNO have two congruent angle pairs (I and N; H and O) and one congruent side (GH and MN). You can use sliders to adjust two of the angles. Use points G and M to drag the triangles and points H and O to rotate them.[br]1. Are GHI and MNO always congruent?[br]2. Is AAS a way to prove that triangles are congruent? Why or why not?[br]3. Look at where GHI and MNO are on your screen. How can you make them merge? How would you describe this movement in terms of transformations?
