19. For the triangles to be congruent, AB must equal DE (or you

could choose 2 other sides to compare)

Distance = 𝑏𝑎𝑠𝑒2 + ℎ𝑒𝑖𝑔ℎ𝑡2

AB = 52 + 42 = 25 + 16 = 41

DE = 42 + 62 = 16 + 36 = 52They are not equal; therefore, the triangles are not congruent.

Distance = 𝑏𝑎𝑠𝑒2 + ℎ𝑒𝑖𝑔ℎ𝑡2

= 52 + 122 = 25 + 144 = 169 = 13

p230 #3, 6, 11, 13, 14, 16, 17, 23b, 24, 35, 44-46 7 points each

For this to be

correct, you must

copy one of the

angles. (SAS)

because x could also equal -3

or ∠LNM or ∠MNL

p238 #1-4, 8-10, 13, 16, 17, 22, 23, 26, 34, 35 [14] 6 points each

For this to be correct, you must

copy two of the angles. (ASA)

Or, in other words, the angles

are not in corresponding places.
