So for this problem, we have the original triangle a, b, c, where a is given in 0, b is given as 8 common 0, and c is given as 2 .7.
00:21
And so the question tells us that each coordinate of each vertex is multiplied by 2.
00:27
To create a similar triangle, a prime, d, prime, c prime.
00:34
And we're trying to find the coordinates of each of these vertices.
00:39
So first off, a prime, well, we just multiply 2 times 0 for the x coordinate of a prime, so we get 0.
00:47
And likewise for the y coordinate of a prime, so a prime is still 0.
00:52
Because even though we multiply each one by 2, since they were originally 0, 2 times 0 is still 0...
