The Lewis dot model of an atom has three dots. Which of the following statements is true about the atom? It has three valence electrons.
It has three innermost shell electrons.
It has three energy levels.
It has three subshells.

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.

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.
