Answer 1

The image below is the final drawing above with the red items added.

Argument Reason

1 Line segment JL is congruent to AB. Drawn with the same compass width. For proof see Copying a line segment

2 The angle KJL is congruent to the angle A Copied using the procedure shown in Copying an angle. See that page for the proof.

3 The angle KLJ is congruent to the angle B Copied using the procedure shown in Copying an angle. See that page for the proof.

4 Triangle JKL satisfies the side length and two angle measure given.
