Triangle ABC is given with the three sides 3, 4, 5. Try to create another triangle with side lengths 3, 4, 5 to see if the triangles are congruent.
1. Triangle ABC is fixed with given lengths and angle measures. Point D is fixed in the second triangle. Move the points E, F and F1 to create another triangle with sides 3, 4, 5. 2. What do you notice about the angle measures of the two triangles? 3. Are these triangles congruent? How do you know? 4. Can you construct any other triangle than the given one? 5. Is Side-Side-Side a way to prove triangles congruent?
