Euler's rotation theorem tells us that any rotation in 3D can be
described by 3 angles. Let's call the 3 angles the Euler angle vector
and call the angles in the vector \(alpha\), \(beta\) and
\(gamma\). The vector is [ \(alpha\),
\(beta\). \(gamma\) ] and, in this description, the order of the
parameters specifies the... | 677.169 | 1 |
ASA vs. AAS: Know the Difference
ASA (Angle-Side-Angle) and AAS (Angle-Angle-Side) are both methods to prove triangle congruence: ASA requires two angles and the included side, AAS two angles and any side.
