I need help with geometry one my question is construct AD congruent to JK​
VARVARA [1.3K]

Answer:

  use your compass to copy the length to a new line

Step-by-step explanation:

To make a line segment that has the same length as another, set your compass width to the length of the one you want to copy, and use that to mark the length on the line where you want your copy.

Use a straightedge to draw a line longer than JK.

  1. Label a point on that line A.
  2. Set your compass to the length JK.
  3. Mark that length from point A on the line you drew. Label the mark D.

AD is congruent to JK.
