Question

If the dimensions of triangle RAH are twice as large as the corresponding dimensions of triangle EAC, calculate length of and . Then, explain if triangle RAH is similar to triangle EAC. Please provide the appropriate postulate(s) to justify your statements

Answer 1

@primeralph

Answer 2

the dimensions are twice--> RA = 2*3.5 =7
AH= 2*6=12
Pythagorean --> RH = \(\sqrt{7^2 +12^2}\) =.....

Answer 3

I don't know what next

Answer 4

It can be similar by SAS postulate

"twice as large"
so RA = 2 times EA
= 2 * 3.5
= ?

and AH = 2 times AC
= 2 * 6
= ?

Answer 5

okay... so what should I do with the dimensions??

Answer 6

okay thanks! i get this!

Answer 7

Glad we could help :)
