help Kyle trying to explain to her friend why the placement of an ange and the concept of rigid motions can be used in determining triangle congruence. She illustrates the SAS triangle corerence and the SSA possibility as shown in the diagram with two pairs of triangles. What do you think Kyle said to her friend about the placement of angles and about the relationship between the triangle pairs in terms of rigid motions? Using Kyle's illustration, write an argument for why the placement of the anges and the concept of rigid motions in proving triangle congruence can be critical A E E
