Inequalities

 

The triangle inequality states that for any triangle, the sum of the lengths of any two sides must be greater than or equal to the length of the remaining side. If a, b, and c are the lengths of the sides of the triangle, with no side being greater than c, then the triangle inequality states that: c ≤ a + b.

 

Theorems on Equalities

 

Theorem 1: If two sides of a triangle are unequal, then the greater side has the greater angle opposite to it.

Theorem 2: If two angles of a triangle are unequal, then the greater angle has the greater side opposite to it.

Theorem 3: Of all the straight lines that can be drawn to a given straight line from a point outside it, the perpendicular is the shortest.
