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 SABC.
• Choose one of the angles on SABC. 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 ADEF 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 ZDEF
and ZEFD
while keeping ZFDEfixed,
Take a screenshot of your results for one position of G, save it, and insert the image in the space below.
