Beyond CPCTC. Lesson 3.4. Medians : Every triangle has 3 medians A median is a line segment drawn from any vertex to the midpoint of its opposite side. A median bisects the segment. B. E. F. A. C. D. Name the 3 medians of triangle ABC. BD CF AE. Altitudes :
A median is a line segment drawn from any vertex to the midpoint of its opposite side.
A median bisects the segment.
Every triangle has 3 altitudes.
An altitude is a line segment drawn perpendicular from any vertex to its opposite side.
*The altitude could be drawn outside the triangle to be perpendicular.
Altitudes form right angles 90˚
You may need to use auxiliary lines (lines added)
AC & CD are altitudes of ABC.
BD & AE are altitudes of ABC
Yes, for an isosceles triangle when drawn from the vertex.
Determine (one and only one line)
