For what type of triangle is the orthocenter always a vertex of the triangle?

A.) Right triangle

Step-by-step explanation:

In a right triangle, the altitude from each acute angle coincides with a leg and intersects the opposite side at (has its foot at) the right-angled vertex, which is the orthocenter.

right triangle

step explanation:

In a right triangle, the altitude from each acute angle coincides with a leg and intersects the opposite side at (has its foot at) the right-angled vertex, which is the orthocenter. The altitudes from each of the acute angles of an obtuse triangle lie entirely outside the triangle, as does the orthocenter H.

also so may i have brainlst it will be my first one ever but if not thats fine as well

a net is a diagram that shows a “flattened” view of a solid. in a net, each face and base is shown with all of its dimensions. a net can also serve as a pattern to build a three-dimensional solid.

a pyramid is a three-dimensional object with a base that is a polygon and triangular faces that meet at one vertex.

" the net of a triangular pyramid consists of four triangles. the base here we are given of the pyramid is a equilateral   triangle, and the lateral faces are also triangles "
