DESCRIPTION
“Special Lines in a Triangle” by Triangle Head. A perpendicular bisector is a line found in a triangle. It cuts the side into two equal parts. And because it's perpendicular it makes two right angles. r. And if you draw all three of them. r. Then you'll notice that they intersect. r. - PowerPoint PPT PresentationTRANSCRIPT
Slide 1
A perpendicular bisectoris a line found in a triangleCIRCUMCENTERIt cuts the side into two equal partsAnd because it's perpendicular it makes two right anglesAnd if you draw all three of themThen you'll notice that they intersectWe have a name for this special pointWe call it circumcenter it's a point that we enjoyrrr
Special Lines in a Triangle by Triangle HeadThere are special lines in a triangleAnd each one of them has a special centerPerpendicular and angle bisectorsThe medians and the altitudes

An angle bisector cuts an angle in twoAnd if you draw all three then they will intersect tooThis center has a name yea it's the incenterDon't worry if it's hard 'cause it will get easierINCENTER
The medians all start at a different vertexAnd to the opposite midpoint they do connectAt the point of intersection is the centroidThat's the third type of center yea now we are overjoyedCENTROIDa2ab2bc2c
There are special lines in a triangleAnd each one of them has a special centerPerpendicular and angle bisectorsThe medians and the altitudes

An altitude is a line that you drawFrom the vertex to the side oppositeIt makes right angles, it's perpendicularAnd where they intersect's the orthocenter
