Write a rotation vector that would rotate the plain green trapezoid onto the other plain green trapezoid (assuming the origin is where the two trapezoids meet).

T = {a b c d}
a= ?
b= ?
c= ?
d= ?

Which is a logical conclusion based on the given information? a. figure abcd is a rhombus by the definition of a rhombus. b. segment ac is congruent to segment dc by cpctc. c. angle acb is congruent to angle adc by the angle-side-angle theorem. d. triangle acd is congruent to triangle cab by the hypotenuse-leg theorem.
