The pair of triangles that are congruent by the asa criterion is . the pair of triangles that are congruent by the sas criterion is .

to be congruent by ASA there must be 2 angles, and the corresponding side (the side connecting the two angles) must be congruent to the same of another triangle

To be congruent by SAS there must be two adjacent sides with the common angle of the two, congruent to these factors of the other triangle

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
