both
orthocenter and circumcenter
You find the orthocenter by constructing the altitudes from the vertices in a triangle. If the triangle is obtuse, the orthocenter will fall outside the triangle. If the triangle is acute, the orthocenter will fall on the inside of the triangle. If the triangle is a right triangle, the orthocenter will lie on a vertix.
The orthocenter may fall outside of a triangle. The orthocenter usually lies within the inside the triangle. However this is only the case if the triangle is acute.
It will, if the triangle is obtuse.
When the triangle is obtuse.
An obtuse angled triangle.
A triangle with one angle bigger than 90 degrees will have its circumscribing circle's centre outside that triangle.
Obtuse triangle! To make this happen the altitude lines have to be extended so they cross.Hope this helps!
Every point in the plane outside the triangle can fall there!
No way! An easy example is the centroid and circumcenter of a right-angle triangle. Circumcenter will be exactly on the middle of the hypotenuse which obviously cannot be the centroid. Centroid is the point where all three lines are connecting all the three vertices and the middle of the line opposite the respective vertex. Circumcenter is the center of the circle passing through all the vertices. As it is known, a right-angle triangle will always fall within a semicircle, meaning the circle center will always be on the middle of the hypotenuse.
It doesn't ever fall outside of a triangle.
A point outside the triangle may.
