Answer: Line of Symmetry means that there should be a line that makes both halfs of the shape, identical.
Step-by-step explanation:
If you draw a line on the girst parallelogram, then you see that the left side does not mirror the right side, thus not being symmetrical. The second shape that looks like a pentagon would by symmetrical and you wold draw the line right down the middle because then the left side would mirror the right side.
The other shape that would work would be the bottom left shape because if you draw a line of symmetry right down the middle of that shape, you can see that both sides are symmetrical and that the left side would mirror the right side.
Answer:
1) Area = 12cm²
2) x = 5cm
Surface area : 69cm²
Step-by-step explanation:
Opposites sides in a rectangle would equal the same.
so Top/bottom = 20+20=40
Front/back = 15+15=30
40+30=70cm²
94-70=24cm² for left and right side 24÷2=12cm²
2) Those lines represents what side it is equal too which also means the same.
3cm, you know that base x height = surface area so surface area ÷ height = base
15/3=5cm
x=5cm
Formula : Base x Height = One surface area
Front/Back= 15+15=30
Top/bottom = 5x3 = 15+15=30
side/side = 3x3=9
30+30+9=69cm²
