Yes, though generally speaking the bottom, horizontal side (if any) of a triangle is called its base.
The base
Vertex angle
They're the 'base angles'.
That is the height of the triangle, the h in the formula a = 0.5b x h
The front of a triangle is typically referred to as the "base." In a triangle, the base is one of the sides and is often chosen to be horizontal for ease of understanding in geometric contexts. The opposite vertex, from which the height is measured, is referred to as the apex or vertex of the triangle.
The base
Vertex angle
The height of a triangle is the perpendicular distance measured from the chosen base (or base extension*) to its opposite vertex (or apex)+.* If any of the shorter sides of an obtuse triangle is chosen to be the base, an extension need to be drawn to this base so that a perpendicular can be constructed from the apex down to this base extension.There are three sides to a triangle, hence three possible bases. Each base will have a corresponding height that is measured from the opposite vertex or apex+.A vertex is the point when 2 sides of a figure intersect.(Read more: vertex)+ A triangle has 3 vertices. 2 vertices defines the length of the base. There remains one vertex that is not touching the base. This vertex is opposite to the base (or base extension) and it is referred to as the apex.

If you mean the vertex where the two equal sides of an isosceles triangle intersect, the side is the base.
Technically, triangles don't have tops or bottoms; triangles are rotatable abstractions. Each of the three lines is called a side and each of the three corners is called a vertex. In more friendly real-world terms, if a triangle is oriented with a side at the "bottom", then the "top" is a vertex; in this case one might call the "bottom" the triangle's base and call the corner at the "top" the vertex opposite the base. If a triangle is oriented with a vertex at the "bottom", then the "top" could be a side or it could be another vertex depending upon the exact shape of the triangle.

1/2 base x height where: base is one of the sides height is the perpendicular distance from the base side to the opposite vertex
The base angles of an isosceles triangle are called the base angles. In an isosceles triangle, two sides are of equal length, and the angles opposite these sides are also equal. This means that the base angles are congruent. The third angle, which is the vertex angle, is located opposite the base.
It does not matter. Any side can be the base. Then, the height is the perpendicular distance between that side and the opposite vertex.
