Which series of transformations demonstrates that the figures are congruent?AReflect Figure A in the y-axis, followed by a reflection in the x-axis. BTranslate Figure A 6 units right, followed by a reflection in the x-axis. CRotate Figure A about the origin 180°, followed by a reflection in the x-axis. DReflect Figure A in the y-axis, followed by a 90° clockwise rotation about the origin.

The answer will be 90 he said it right?

Step-by-step explanation: 90 is the right angel

3. parallelogram

step-by-step explanation:

we turn each of our sides into direction vectors

ab=b-a=(3 - 7, 1 - 0) = (-4, 1)

bc=c-b=(1,6)

cd=d-c=(4,-1)

da=a-d=(-1,-6)

we see how the opposite sides have negated direction vectors; this is characteristic of a parallelogram.   we have congruent sides ab=cd and bc=da with unequal lengths because 1^2+6^2 is different from (-4)^2+1^2.   so it's not a square or a rhombus.  

we check the dot product of direction vectors of adjacent sides.   we have

ab dot bc = -4(1) + 1(6) = 2

that's not zero so the sides are not perpendicular.   we've ruled out rectangle.

the direction vectors indicate two pairs of congruent parallel sides, so we choose parallelogram over trapezoid.

hey! so 1 (25) out of 4 (100) is 25 so your answer is 25%. it's like quarters!
