Step-by-step explanation:
<u>Given triangle EFG:</u>
- E(0, 5), F(1, 1), G(-2, 1)
- Center of dilation is H(0, 1)
- Scale factor is k = 3
<u>The rule for this dilation is:</u>
- (x, y) → (k(x - a) + a, k(y - b) + b)
- (x, y) → (3x, 3(y - 1) + 1) = (3x, 3y - 2)
<u>The coordinates of E'F'G' are:</u>
- E → E' = (0, 5) → (0, 13)
- F → F' = (1, 1) → (3, 1)
- G → G' = (-2, 1) → (-6, 1)
- Points H and H' overlap as center of dilation at (0, 1)
<u>Options (verified with the graph):</u>
Segment EH and segment E prime H prime both pass through the center of dilation.
- True
The slope of segment EF is the same as the slope of segment E prime H prime.
- False
Segment E prime G prime will overlap segment EG.
- False
Segment EH ≅ segment E prime H prime.
- False
