The drawing shows a compass and straight edge construction of...what?
the bisector of a given angle
a perpendicular to a given line at a point on the line
a perpendicular to a given line from a point NOT on the line
an angle congruent to a given angle
Cash constructed a segment bisector as shown. What is true about the segment bisector? Select all that apply.
It is perpendicular to segment AB
It divides segment AB into two congruent segments
It is exactly the same length as segment AB
It intersects segment AB at the midpoint
Erick was attempting to construct a perpendicular bisector to the segment with a compass and straight edge.
Which of the below statements explains what Erick may have done wrong?
Erick should have started with the needle at the midpoint of segment AB
Erick should have opened his compass to a bigger radius over half the length of segment AB
On step #2, Erick should have placed the needle where the first arc intersected segment AB
Erick needs to now connect the opposite arc endpoints with a straight edge to see where they intersect
