Name: _______________________ Class: ______________________ Date:_______________________ Proving Side-Side-Side Similarity Begin: Step 1: Create a triangle with the follow side lengths: 4 inches, 6 inches, and 8 inches. Step 2: Create a second triangle using a scale factor of 2.5. 4 Step 3: Create a third triangle using a scale factor of 5. Step 4: Determine if these three triangles are similar by measuring the angles. List the length of your sides and angles: Side 1 Side 2 Side 3 Angle 1 Angle 2 Angle 3 Triangle 1 Triangle 2 Triangle 3 Were your three triangles similar? How do you know this? Proving Side-Angle-Side Similarity Begin: Step 1: Create a 55° angle. Its two sides should be 3.5 and 5 inches long. Enclose your angle to make a triangle. Step 2: Create a second 55° angle. Use a scale factor of ¾ to find the length of your sides. After creating these sides, enclose your angle to make a triangle. Step 3: Create a third 55° angle. Use a scale factor of 2 to find the length of your sides. After creating these sides enclose your angle to make a triangle. List the length of your sides and angles: Side 1 Side 2 Triangle 1 Triangle 2 Triangle 3 Were your three triangles similar? How do you know this?
