Discovery of More Triangle Similarity Shortcuts

For SSS: make sure that you pick a scale factor to make your triangle have proportional sides with MY triangle (look up at the board). Drag C and C1 to create a triangle (you will know you are good when the angle bubbles fill in). Once your triangle is created, click the "See Angle Measures" checkbox. Do we have similar triangles???

SSS Similarity

For SSA: make sure that you pick a scale factor to make your triangle have proportional sides with MY triangle (look up at the board). We also all need to have the same angle A. Drag C and C1 to create a triangle (you will know you are good when the angle bubbles fill in). Once your triangle is created, click the "See Angle Measures" and "See Side Lengths" checkboxes. Do we have similar triangles???

SAS Similarity

For SSA: make sure that you pick a scale factor to make your triangle have proportional sides with MY triangle (look up at the board). We also all need to have the same angle B. Drag C and C1 to create a triangle (you will know you are good when the angle bubbles fill in). Once your triangle is created, click the "See Angle Measures" and "See Side Lengths" checkboxes. Do we have similar triangles???
