Inequalities In Two Triangles

The triangle inequality says a detour is never shorter than going straight. ‖u + v‖ ≤ ‖u‖ + ‖v‖ Equality holds exactly when u and v are parallel and point the same way; in the general case the direct vector u + v is strictly shorter than following u then v. The same statement reappears for real numbers as |a + b| ≤ |a| + |b| and for integrals as |∫f| ≤ ∫|f|, with the reverse form ‖u‖ − ‖v‖ ≤ ‖u − v‖ often the more useful of the two. This single inequality is what makes a distance a distance.

Proves Inequalities In A Triangle

Testing triangle sides for geometry can be as simple as cutting strips of paper in various measures. Allow students to test the various combinations to see if a triangle can be formed. Then as a class, establish the triangle rule that the sum of the lengths of any two sides of a triangle has to be greater than the length of the third side. Save this hands on math activity for later and follow me for more middle school math tips.

Triangles are among the most fundamental shapes in geometry, and their properties help us understand countless mathematical and real-world concepts. One of the most important properties of triangles is expressed through the Triangle Inequality Theorem — a principle that determines whether three given line segments can form a triangle.
