Kyra is using rectangular tiles of two types for a floor design. A tile of each type is shown below: Which statement is correct?
The two tiles are not similar because segment SP is to segment SR is 5 : 1 and segment MJ is to segment ML is 2 : 3. The two tiles are similar because segment PQ is to segment QR is 1 : 3 and segment JK is to segment KL is also 1 : 3. The two tiles are similar because segment SR is to segment SP is 3 : 2 and segment ML is to segment MJ is also 3 : 2. The two tiles are not similar because segment PQ is to segment QR is 1 : 6 and segment JK is to segment KL is 1 : 3.
@ganeshie8 Can you please help me? :)
what are the dimensions of firsr tile ?
simply subtract x coordinates for width and subtract y coordinates for height
um i don't remember this stuff.
look at the first tile : PQRS what are the coordinates of points P and Q ?
2,2 4,2
P = (2, 2) Q = (4, 2) whats the difference in x coordinates ?
4 and 2
subtract
2
Yes, so width = PQ = 2 what about height ?
height = QR what are the coordinates of Q and R ?
4,2 4,8
it would be 6
right?
Perfect! so the dimensions of first tile are : width = 2 height = 6
similarly can you find the dimensions of second tile ?
3,3?
try again
whats the width of second tile ?
0,3?
how can the width be 0 ?
width of second tile = JK what are the coordinates of JK ?
i meant 1, 3
Yes! for second tile width = 1 height = 3
so width/height ratio is `1/3`
whats the width/height ratio for first tile ?
yeah, ohh and the 2/6 is reduced into 1/3 so the answer is B?
Yes! since the ratios are equal, the tiles are similar.
B is right!
Thank you so much!
