Answer:
a) ∅ ∈ {∅} TRUE
b) ∅ ∈ {∅,{∅}} TRUE
c) {∅} ∈ {∅} FALSE
d) {∅} ∈ {{∅}} TRUE
e) {∅} ⊂ {∅,{∅}} TRUE
f ) {{∅}} ⊂ {∅,{∅}} TRUE
g) {{∅}} ⊂ {{∅},{∅}}FALSE
Step-by-step explanation:
To assess whether these statements are true or false, first observe the symbol:
"∈" means that element, as it is and as it is, belongs to the set. To belong to the set it must be within the symbols "{}"
On the other hand, the symbol "⊂" means "subset", that is, it is a subset that is included in the main set.
So:
c) is false because "{∅}" is not included in the set
g) is false because " {{∅}}" is not included in the set
You would have to plot the vertices and play a sort of game of connect the plots ( *Or connect the dots but more literally, the plots*) Then decide whether or not your final illustrations have the potential to be similar. If so, why?
EXAMPLE ANSWER: DO NOT USE ANY IF THEM BELOW FOR I DO NOT KNOW THE UNIT LENGTH OR SHAPE THE CONNECTED DOTS WOULD CREATE!!!
The two triangles could be similar due to the identical amount of units between each vertice. Furthermore, you could connect the units in a certain orientation, keeping the units in mind, and produce two identical triangles.
Or...
The two triangles could be similar due to the type of triangle. Each triangle has the potential to be a (right/scalene/isosceles/obtuse/acute, etc).
