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

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
