In today's class, we started by correcting yesterday's homework, which mainly involved Theorem 5-12, which we learned yesterday.

Afterwards, we went to geogebra to understand SAS Inequality and the SSS Inequality.

Theorem 5-13: SAS Inequality: If two sides sides of a triangle are congruent to two sides of another triangle and if the included angle in one triangle is greater than the included angle of the other triangle, then the 3rd side of the first triangle is greater than the 3rd side of the second triangle.

Theorem 5-14: SSS Inequality: If two sides of the first triangle are congruent to two sides of the second triangle and the third side in the first triangle is greater than the other third side, then the angle between the pair of congruent sides in the first triangle is greater than the corresponding angle in the second triangle.

Majority of the class didn't finish the both theorems, so we should finish the geogebra activity tomorrow.

No homework is due tomorrow but please keep in mind that on Friday (the 21st) we have a quiz and our test will be on Wednesday, next week (the 26th).

That's all. :)
