Angle and Side Relationships The interior angles of any triangle always sum to exactly 180 degrees, a rule that serves as the bedrock for deriving other geometric rules for triangles. The area can be calculated using the formula involving base and height, Heron's formula with side lengths, or the trigonometric formula using two sides and the included angle.

Furthermore, the side opposite the largest angle is always the longest side, and conversely, the largest angle is always opposite the longest side, establishing a clear hierarchy within the shape. Similarly, the Angle-Angle (AA) similarity criterion confirms that triangles sharing two equal angles have proportional sides, regardless of their absolute dimensions.
Furthermore, the side opposite the largest angle is always the longest side, and conversely, the largest angle is always opposite the longest side, establishing a clear hierarchy within the shape. Classification by Sides and Angles Triangles are primarily categorized based on the relative lengths of their sides and the magnitude of their internal angles.

This relationship allows for the calculation of an unknown side when the other two are known, forming the basis for distance measurements and vector calculations. From a side-length perspective, an equilateral triangle features three congruent sides, resulting in three identical 60-degree angles.
