Similarity - Two pairs of proportionate sides (1 Viewer)

[Joshmosh2]

To prove similarity using the 'one corresponding pair of angles are equal and two pairs of sides are in proportion'
Can you prove similarity with one or two unknown variables within the proportions?
If so, does that mean you can consider them 'similar' even though some corresponding sides are unknown?

You can prove similarity with unknown variables, as long as there's a condition that ties them together to produce a legit ratio.

So with two triangles, to find any ratio, you would need at least 2 known sides?

similar triangles could use
- SAS in ratio
- AA (equaianular)
- RHS in ratio
