In this chapter you will learn the properties of perpendicular and angle bisectors as well as the inequalities in one and two triangles. We will touch base on special points, segments and lines related to triangles. You will also apply Pythagorean Theorem to learn about Pythagorean inequalities and special right triangles. Indirect proofs are our next form of proof that we will learn about.
