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
Slide 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
Slide 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
Slide 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

There are special lines in a triangle And each one of them has
a special center Perpendicular and angle bisectors The medians and

Slide 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
