Marisa is constructing a congruent segment.
What should her next step be?
A ____________ B
C ________________
1)Draw an arc intersecting ray C and
label the point of intersection as D
2) Open the compass to the length of AB
3) Draw a ray with endpoint C
4) Keep the compass open to the same
width and point your point on C
What is the missing step in constructing a congruent angle?
X
Y
________
S
________
Z
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.
Put the steps in order for constructing a
perpendicular bisector:
A ____________ B
1) Draw a segment connecting the two intersections
above and below the line
2) Use the same opening on the compass, put the
point on B and draw another arc intersecting AB
3) Put the point on A and open the compass more than
half way
4) With the point on A, draw an arc intersecting AB.
