Answer:
Connect arcs that are above the original line with a straightedge ⇒ 2nd
Step-by-step explanation:
* <em>Lets revise how to construct a perpendicular line through a point</em>
<em> on the line</em>
- <u>Given:</u> line AB and point P lies on it
1. Place your compass pin at P and draw an arc of any size below
AB that crosses the line twice at points C and D
2. Stretch the compass to a larger distance
3. Place the compass pin on point C and draw a small arc above
the line
4. Without changing the distance of the compass place the
compass pin on point D and draw another small arc intersects
the small arc from C at point E
5. <u>Using a straightedge, to join P which is on the original line and E </u>
<u>which is the intersection point of the two small arcs above the </u>
<u>original line,</u> then PE is perpendicular to AB at E
- From the steps up the step is including in the construction of a
perpendicular line through a point on a line is:
<u><em>Connect arcs that are above the original line with a straightedge</em></u>
* <em>Remember:</em>
- The step of Connect arcs that are above and below the given line
with a straightedge is in the construction a perpendicular from a
point off the line
- The step of Create arcs on either side of a point that is off the
given line is in the construction of a perpendicular bisector
of a line
- The step of Create a copied angle by using the first two lines as the
original angle in the construction of the parallel lines
