Question

In the diagram, which must be true for point D to be an orthocenter?


BE, CF, and AG are angle bisectors.

BE ⊥ AC, AG ⊥ BC, and CF ⊥ AB.

BE bisects AC, CF bisects AB, and AG bisects BC.

BE is a perpendicular bisector of AC, CF is a perpendicular bisector of AB, and AG is a perpendicular bisector of BC.

Answer 1

The second expression must be true that D would be the ortocenter of the triangle.

'BE ⊥ AC, AG ⊥ BC, and CF ⊥ AB.'

because the ortocenter is found at the intersection of the 3 heights
