Side-Side-Angle - The Ambiguous Case

This application allows you to view the ambiguous case of Side-Side-Angle and illistrate why two triangles with Side-Side-Angle cannot prove triangle congruency. Move the slide to determine how many triangles you want to be shown. Adjust the angle slider to try and make a triangle with the side lengths. Remember for Side-Side-Angle, two sides and an angle are fixed, where two angles and a side (the dotted line) can have any measure.
