The segment that passes through a vertex and is perpendicular to the opposite side is called the altitude of the triangle.
equilateral triangles
It is a straight line which passes through the vertex of the angle and divides it into halves.
and is perpendicular to the opposite side.
Altitude.
perpendicular
side
Yes, provided that the base is not one of the 2 equal sides. And it's also the perpendicular bisector of the base.
An angle comprises to rays meeting at a vertex. An angle bisector is a straight line through the vertex which bisects the angle.
The perpendicular bisector bisects the angle at the vertex.
A median of a triangle is a line or segment that passes through a vertex and bisects the side of the triangle opposite the vertex.
Yes. If you have an isosceles triangle standing up on the unequal side, thenthe line segment from the top vertex perpendicular to the base is all of these.
