An orthocenter is the intersection of three

Altitudes in a triangle

A centroid is the intersection of three

Medians in a triangle

ABC is an obtuse triangle. Which is true about point D?

Point D cannot be the orthocenter because the orthocenter of an obtuse triangle is located outside the triangle.

What is EB?

XXX 6 icnhes

In the diagram, JG = 5 cm and GE = 10 cm. Based on this information, can G be a centroid of triangle LMN?

XXX Point G can be a centroid because GE and JG are in the ratio 2:1. XXX Point G cannot be a centroid because JG does not equal GE.

Which is the final step to complete the proof?

XXX Write a linear equation for each side of the triangle.
