width and point your point on C 

Marisa is constructing a congruent segment. What should her next step be?

 ____________ ________________A B C

Steps:1) Draw a ray. Label the endpoint S.2) Put the compass tip at Y and draw an arc that intersects both YX and YZ.3) ___________________________________________________________4) Adjust the compass width so that tip and the pencil are at the points where the arc intersects YX and YZ.5) Keeping the compass width, put the tip at T and draw an arc that intersects that first arc. 6) Label the point R and connect S to R in a ray.

a) Given YX, draw any line SR intersecting YX.b) Keep the compass open to the same width. Put the tip at S. Draw and arc intersecting the ray at point T.c) Open the compass to more than half the length of YX. Put the tip on Y and draw an arc intersecting YX.d) With the point on X, draw an arc in between the rays.
