draw a line segment AB to be 3 cm long. the, draw line segment DC so that it is congruent, but not parallel, to line segment AB

To draw a line segment AB that is 3 cm long:

1. Take a ruler and place one end (point A) at the starting point.
2. With the other end of the ruler, measure 3 cm from point A and make a small mark. This will be point B.
3. Connect point A and point B with a straight line using a pencil. This line segment AB is now 3 cm long.

To draw a line segment DC that is congruent to line segment AB:

4. Place the ruler on the paper in a different location from line segment AB.
5. With one end of the ruler, measure the same length as line segment AB (in this case, 3 cm) and make a small mark. This will be point D.
6. Without changing the measurement, move the other end of the ruler to point D and make another small mark. This will be point C.
7. Connect point D and point C with a straight line using a pencil. This line segment DC is now congruent to line segment AB.

Note: To ensure that line segment DC is not parallel to line segment AB, make sure the two lines do not have the same slope or are in the same direction.

To draw a line segment AB that is 3 cm long, you will need a ruler, a pencil, and a blank sheet of paper. Here's how you can do it:

1. Take your ruler and place it horizontally on the paper.
2. Use the pencil to make a small mark on the paper to indicate point A.
3. Starting from point A, measure a distance of 3 cm on the ruler.
4. With the pencil, make another small mark on the paper to indicate point B, aligning it with the 3 cm mark on your ruler.
5. Now, you have successfully drawn a line segment AB that is 3 cm long.

To draw a line segment DC congruent to AB but not parallel, follow these steps:

1. From point B, draw a line segment extending downward or upward at any angle you prefer. This line will represent line segment DC.
2. Measure the length of line segment AB (3 cm) and mark a point on the line segment DC that is equidistant from its endpoints.
3. Use a pencil to make a small mark on the line segment DC to indicate point D.
4. Finally, draw a line segment connecting point C and D.
5. You have now successfully drawn line segment DC, which is congruent to AB but not parallel.

Remember that congruent line segments have equal lengths, while parallel lines never intersect.
