What will be constructed if you draw segments AB and AC?
A perpendicular bisector of BC
An isosceles triangle
An obtuse triangle
An equilateral triangle
What can you tell about lines m and n and why?
they are perpendicular due to congruent corresponding angles, so by the Parallel Lines Conjecture
they are parallel due to congruent corresponding angles, so by the Converse of the Parallel Lines Conj.
they are parallel due to the congruent corresponding angles so by the Parallel Lines Conjecture
they are parallel due to the congruent alternate exterior angles, so by the Parallel Lines Conj.
If you made a triangle with C, D, and the black point we'll call E, what would the segment from E to segment CD be called?
altitude
median
perpendicular bisector
angle bisector
Eric was attempting to construct a perpendicular bisector to the segment AB with a compass and straight edge. Which of the below statements explains what Eric may have done wrong?
Eric should have started by putting the compass needle point at the midpoint of the segment AB.
On the second step, Eric should have placed the compass needle point where the first arc intersected the segment AB.
Erick just needed to open the compass more to create arcs that have a radius of more than half the length of the segment AB.
Erick didn’t do anything wrong he just needs to connect the opposite endpoints of each arc to finish the construction.
What does PC represent in the accompanying construction?
the perpendicular bisector of AB
the angle bisector of <APB
