A quick trick I learned is that the longest side is the angle that does include both letters. For example, $\angle$A does not include letter B or C, therefore $\overline{BC}$ is the longest side.
45$^{\circ}$, 65$^{\circ}$, 70$^{\circ}$
$\angle$B $\angle$C $\angle$A
Side length $\overline{BC}$ is the longest side because the largest angle does not include the letters B or C in the triangle.
