A statement or proposition which is regarded as being established, accepted, or self-evidently true
The answer is all 3 of them. Transformations are isometries if distance between all dots are maintained the same. Easier way of spotting these is to check if all angles and all sides of surfaces are the same as before.
First and second we flipped horizontaly while last one we flipped both verticaly and horizontaly but sides and angles remained the same.
Answer:
x = 14
Step-by-step explanation:
As we can see that the bottom side is equivalent to 3 of the smallest triangle and the side of the larger triangle is equivalent to the 9
This represents that it is dilated by 3 factor
So
= 3 × 3
= 9
Now the other side i.e. 5 of the smallest triangle also need to be dilated by a 3 factor
So the new side is 15
Also the largest triangle is x + 1
So,
15 = x + 1
x = 14
A minute less than 1 hour, to be exact.
