The video tutorial explains the angle-side theorem, which states that in a triangle, the longest side is opposite the largest angle, and the shortest side is opposite the smallest angle. It provides examples to illustrate how to calculate missing angles and determine the longest side based on given angles and side lengths. The tutorial also covers scenarios where triangles have equal longest sides, explaining how to identify the corresponding largest angles.

What does the angle-side theorem state about the relationship between angles and sides in a triangle?

• The shortest side is opposite the largest angle.

• The longest side is opposite the smallest angle.

• All sides are equal in length.

• The longest side is opposite the largest angle.
