In this lesson our instructor talks about the inequalities involving two triangles. First she talks about the SAS inequality theorem. Then she talks about the SSS inequality theorem. Four complete extra example videos round up this lesson.
SAS (Side-Angle-Side) Inequality Theorem (Hinge Theorem): If two sides of one triangle are congruent to two sides of another triangle, and the included angle in one triangle is greater than the included angle in the other, then the third side of the first triangle is longer than the third side in the second triangle
SSS (Side-Side-Side) Inequality Theorem: If two sides of one 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
