2. A perpendicular bisector is a line found in a triangle CIRCUMCENTER It cuts the side into two equal parts And because it's perpendicular it makes two right angles And if you draw all three of them Then you'll notice that they intersect We have a name for this special point We call it circumcenter it's a point that we enjoy r r r “Special Lines in a Triangle” by Triangle Head

3. There are special lines in a triangle And each one of them has a special center Perpendicular and angle bisectors The medians and the altitudes a 2a b 2b 2c c

4. An angle bisector cuts an angle in two And if you draw all three then they will intersect too This center has a name yea it's the incenter Don't worry if it's hard 'cause it will get easier INCENTER

5. The medians all start at a different vertex And to the opposite midpoint they do connect At the point of intersection is the centroid That's the third type of center yea now we are overjoyed CENTROID a 2a b 2b c 2c

6. There are special lines in a triangle And each one of them has a special center Perpendicular and angle bisectors The medians and the altitudes a 2a b 2b 2c c

7. An altitude is a line that you draw From the vertex to the side opposite It makes right angles, it's perpendicular And where they intersect's the orthocenter ORTHOCENTER
