Down you can see a triangle, which is reflected across the line t. Grab the line and triangle CDE to move them. Grab the points C,D,E to change the shape of the triangle. 1. What are your observations about the angles of triangle DCE and the angles of the reflected triangle? (For the solution click on the checkbox Angles.) 2. What are your observations about the length of the sides of the triangles? (For the solution click on the checkbox Sides.) 3. How would you construct a reflected triangle?
