<p>Hello,</p>
<p>Do we need to know ambiguous triangles for the sat 2 math? Thanks! </p>
<p>In what context? For example, the fact that you cannot uniquely determine the third side of a triangle given two sides and one of its angles.</p>
<p>If so, I highly doubt it, and if it does, it’s not difficult to learn that you can’t use SSA as a congruence postulate.</p>
<p>Yeah, the ambiguous cases SSA. It is in the barrons book and I heard that its not tested (not sure if that is true) so I was wondering if I should still review it because I totally forgot about it. </p>
<p>Oh. Many books might mention it (especially geometry) since SSS, ASA, SAS can be used to show congruence, but SSA can’t necessarily be used.</p>
<p>Don’t worry too much about whether you should “review” it since it literally takes 30 seconds to explain.</p>
