Select the figure with no line symmetry and a rotational symmetry angle of 180 degrees.
a.
b.
c.
d.

C.

Step-by-step explanation:

In the image shown below, A, B, and C all have a line of simmetry, which basically is that if you create a line and fold the image the resultant would be two exact halfs of image, in the case of A you have to draw a diagonal line and fold backwards, in b you draw a line in the middle and fold to the fron and in D you do the same, only C has no line simmetry, but has a symmetry angle of 180º, meaning that if you rotate the figure 180ª the resultant image would be the exact same.

arrange the equations with like terms in columns.

analyze the coefficients of x or y.

add the equations and solve for the remaining variable.

substitute the value into either equation and solve.

check the solution.
