If δabc ≅ δedf where the coordinates of a(−1, 1), b(2, 4), and c(3, 1), what is the measure of ef?

answer:

since δabc ≅ δedf, ef ≅ ac, ed ≅ ab, and df ≅ bc

length of ef = √[())2 + (1-1)2] = 4

step-by-step explanation:

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.

7,24
