Respuesta :

C because all the angles are acute

Answer:

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.
