parts of triangle
median
from a vertex to midpoint
meet at centroid
cut medians in 2:1
divides triangle into 6 equal parts
midline theorem
median to hypotenuse is half hypotenuse
right triangle
30 60 90 triangle
90 45 45 triangle
pythagorean triplets
satisfies pythagorean theorem
\(a^2+b^2=c^2\)
common examples
9, 40, 41
7,24,25
3,4,5
5,12,13
bisectors
angle
cut angles in half
line consisting of all points which are the same distance from both sides of triangle
in triangle
meet at incenter
drawn inside
angle bisector theorem
area of triangle=inradius*semi perimeter
perpendicular
cut line segment in half
line consisting of all points which are the same distance from both ends of triangle
perpendicular to segment
in a triangle
all meet at circumcenter
circle drawn outside with a b and c on the circumference
circumradius is half hypotenuse in right triangle
