Verticy, or vertices
I think it's circumcenter of the triangle if you stare at the question long enough. Like where the the three ?vertices? are meeting in the middle.
They are the lines joining each of the vertices to the mid-points of the opposite sides. In an equilateral triangle, these lines are the medians, angle bisectors, altitudes and perpendicular bisectors of the sides - all in one!
A scalene triangle. The sides are all different lengths -- 5, 2sqrt(5) and sqrt(5)

36. If the length of the line segment joining the midpoints of two sides of an equilateral triangle is 6 the perimeter of the triangle is 36.
midsegment
A scalene triangle. The sides are all different lengths -- 5, 2sqrt(5) and sqrt(5)
The are the intersection points of the line segments that make up the sides, in other words the corners of the triangle.
A scalar triangle is a triangle in which all sides have different lengths. To construct a scalar triangle, start by drawing three non-collinear points that will represent the vertices of the triangle. Then, connect the points with straight lines to form the sides of the triangle such that no two sides are of the same length.
isosceles triangle
They are the three points at which the sides of a triangle meet - in pairs.
