Now you’ll attempt to copy your original triangle using two of its angles: Choose two of the angles on ∆ABC, and locate the line segment between them. Draw a new line segment, DE, parallel to the line segment you located on ∆ABC. You can draw DE of any length and place it anywhere on the coordinate plane, but not on top of ∆ABC.

From points D and E, create an angle of the same size as the angles you chose on ∆ABC. Then draw a ray from D and a ray from E through the angles such that the rays intersect. You should now have two angles that are congruent to the angles you chose on ∆ABC.

Label the point of intersection of the two rays F, and draw ∆DEF by creating a polygon through points D, E, and F.
