Question

Use the figure to find the length HJ. Assume △DEF ≅ △GHJ. *I GOT 30*

Answer 1

Yes, HJ = 30 ft.

It tells us that triangle DEF = triangle GHJ.

By seeing this we know without looking at the triangles that EF is going to be the same as HJ because when they say a figure is the same as another and list the letters such as 'DEF' and 'GHJ' they will list them in the same order.

So

'DEF' = 'GHJ' we get:

'DE' = 'GH'

'EF' = 'HJ'

And we can do the last and first letters:

'FD' = 'JG'

And since we know 'EF' = 'HJ' and that they already told us 'EF' was 30, we know HJ will be 30.
