In triangle ABC, angle A = 110 °, angle B = 55 °. Pick the smallest side of the triangle.

And so for the beginning we need to find all the corners of the triangle.

angle A = 110 °, angle B = 55 °

110 ° + 55 ° = 165 ° (angle A + B),

180 ° – 165 ° = 15 ° (angle C).

Here we must remember the rule that the largest side is opposite the largest corner of the triangle, the middle side is opposite the middle corner, and the smallest side is opposite the smallest corner.

It follows that the smallest side of the triangle AB because opposite the side AB is the angle C which is the smallest in the triangle ABC.
