KL and MN are parallel lines. O is the midpoint of segment LM. Which transformation of the plane can we use to prove angles u and v are congruent, and why?
a) A reflection over a line through O that is parallel to KL and MN maps ray LK onto MN and vice versa, and the same for rays LO and MO on top. This means angle u will be mapped onto angle v and vice versa.
b) A translation along the directed line segment ML maps line MN onto line KL and angle v onto angle u.
c) A 180 degree rotation about O maps ray LK onto MN and vice versa, and the same for rays LO and MO. This means angle u will be mapped onto angle v and vice versa.

Jonathan pays $1.90 per pound for potatoes. he buys 8.3 pounds of potatoes. he determines that he will pay $15.77, before tax, for the potatoes. which best describes the reasonableness of jonathan’s solution? jonathan’s answer is reasonable because there are two decimal places in the factors and two in the product. jonathan’s answer is unreasonable because there are three decimal places in the factors and two in the product. jonathan’s answer is reasonable because is 16, and 16 is close to 15.77. jonathan’s answer is unreasonable because is 8, and 8 is not very close to 15.77.
