Part A Create a random triangle, ΔABC. Measure and record its angles.
Angle Measure
∠ABC 36.87°
∠ACB 90°
∠CAB 53.13°

Part B

Now you will attempt to copy your original triangle using one of its angles:

Draw a line segment, DE , of any length anywhere on the coordinate plane, but not on top of ∆ABC.

Choose one of the angles on ∆ABC. From point D, create an angle of the same size as the angle you chose. Then draw a ray from D through the angle. You should now have an angle that is congruent to the angle you chose on ∆ABC.

Create a point anywhere outside the mouth, or opening, of the angle you created. The point will initially be named F by the tool, but you should rename it point G. Now draw a ray from E through G such that it intersects the first ray. Your creation should be a closed shape resembling a triangle.

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

Click on point G, and move it around. By moving point G, you can change DEF and EFD, while keeping FDE fixed.

Take a screenshot of your results for one position of G, save it, and insert the image in the space below.
