Multiple Choice

****Which best explains whether or not ΔABC ≅ ΔLMN? #32

• The figures are congruent because a 270° rotation about the origin and then a reflection over the x-axis will map ΔABC onto ΔLMN.

• The figures are congruent because a 180 rotation about the origin and then a reflection over the x-axis will map ΔABC onto ΔLMN.

• The figures are not congruent because point B corresponds with point N and point C corresponds with point M.

• The figures are not congruent because there is no rigid transformation or combination of rigid transformations that will map ΔABC onto ΔLMN.

Multiple Choice

What type of construction do you see? #30

• midpoint

• angle bisector

• perpendicular bisector

• altitude

Multiple Choice

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? #31

• 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.

12.1 Triangle Proportionality Theorem

"Winners are not people who never fail but people who never quit."

Corresponding Angles

The corresponding angles definition tells us that when two parallel lines are intersected by a third one, the angles that occupy the same relative position at each intersection are known to be corresponding angles to each other.

Multiple Choice

What is the definition of the side splitter theorem? #43

• if a line is parallel to a side of a triangle and the line intersects the other two sides, then this line divides those two sides congruently.

• if a line is parallel to a side of a triangle and the line intersects the other two sides, then this line divides those two sides proportionally.

• If the three sides of one triangle are congruent to the corresponding sides to another triangle, then the two triangles are congruent.

• If the three sides of one triangle are congruent to the corresponding sides to another triangle, then the two triangles are proportional.
