If angle B in triangle ABC is obtuse, then: BC – smaller side AB – large side AB – smaller side

If angle B in triangle ABC is obtuse, then: BC – smaller side AB – large side AB – smaller side BC – large side AC – smaller side AC – large side

There can be only one obtuse angle in a triangle, and it will be the largest of all three angles. By the theorem on the ratio between the sides and angles of a triangle (In a triangle opposite a larger angle lies a larger side). opposite the obtuse angle lies the large side of the speaker.

The speaker side will be the largest of the three sides. If you need to compare only two sides of the AC and BC, then AC> BC.

Two sides AB and BC – it is impossible to compare, because we do not know the value of which of the angles A or C is greater.

Answer. Of the two sides AB and BC, BC is the smaller side, AC is the larger side.
