Answer – Angle Measure
Generally speaking, when similarity transformations are performed on a triangle, the angle measure is preserved, whereas the length of the sides may be enlarged or reduced depending on the scale factor of the transformation, thus giving rise to similar triangles with corresponding angles that have exactly the same measure and corresponding sides that are proportional.

Question
------------------------------------------------------------------
![\boxed { \frac{n+h}{5} = \frac{f+9}{9}}](https://tex.z-dn.net/?f=%20%5Cboxed%20%7B%20%5Cfrac%7Bn%2Bh%7D%7B5%7D%20%20%3D%20%20%5Cfrac%7Bf%2B9%7D%7B9%7D%7D%20)
------------------------------------------------------------------
Split the fraction on the left
------------------------------------------------------------------
![\boxed { \frac{n}{5} + \frac{h}{5} = \frac{f + 9}{9}}](https://tex.z-dn.net/?f=%5Cboxed%20%7B%20%5Cfrac%7Bn%7D%7B5%7D%20%2B%20%5Cfrac%7Bh%7D%7B5%7D%20%20%3D%20%5Cfrac%7Bf%20%2B%209%7D%7B9%7D%7D%20)
------------------------------------------------------------------
Take away h/5 from both sides
------------------------------------------------------------------
![\boxed { \frac{n}{5} = \frac{f+9}{9} - \frac{h}{5}}](https://tex.z-dn.net/?f=%5Cboxed%20%7B%20%5Cfrac%7Bn%7D%7B5%7D%20%20%3D%20%5Cfrac%7Bf%2B9%7D%7B9%7D%20-%20%5Cfrac%7Bh%7D%7B5%7D%7D)
------------------------------------------------------------------
Change the denominator to be the same
------------------------------------------------------------------
![\boxed { \frac{n}{5} = \frac{5f+45}{45} - \frac{9h}{45}}](https://tex.z-dn.net/?f=%5Cboxed%20%7B%20%5Cfrac%7Bn%7D%7B5%7D%20%3D%20%5Cfrac%7B5f%2B45%7D%7B45%7D%20-%20%5Cfrac%7B9h%7D%7B45%7D%7D%20)
------------------------------------------------------------------
Put it into single fraction
------------------------------------------------------------------
![\boxed { \frac{n}{5} = \frac{5f+45-9h}{45} }](https://tex.z-dn.net/?f=%5Cboxed%20%7B%20%5Cfrac%7Bn%7D%7B5%7D%20%3D%20%5Cfrac%7B5f%2B45-9h%7D%7B45%7D%20%7D)
-------------------------------------------------------------------
Rearrange (This step may not be necessary)
------------------------------------------------------------------
![\boxed {\frac{n}{5} = \frac{5f-9h+ 45}{45} }](https://tex.z-dn.net/?f=%20%5Cboxed%20%7B%5Cfrac%7Bn%7D%7B5%7D%20%3D%20%5Cfrac%7B5f-9h%2B%2045%7D%7B45%7D%20%7D)
