Title: Inequalities Involving Two Triangles


1
Inequalities Involving Two Triangles
  • SAS Inequality/Hinge Theorem
  • If two sides of one triangle are congruent to two
    sides of another triangle and the included angle
    in one triangle has a greater measure than the
    included angle in the other, then the third side
    of the first triangle is longer than the third
    side of the second triangle.

Inequalities Involving Two Triangles
  • SSS Inequality
  • If two sides of a triangle are congruent to two
    sides of another triangle and the third side in
    one triangle is longer than the third side in the
    other, then the angle between the pair of
    congruent sides in the first triangle is greater
    than the corresponding angle in the second
    triangle.
