A circumconic passing through the orthocenter of a triangle is a rectangular hyperbola. In any acute triangle, the inscribed triangle with the smallest perimeter is the pedal triangle of the orthocenter (the triangle whose vertices are the feet of the perpendiculars from the orthocenter to the sides).
Recall that an isosceles triangle is a triangle with at least two congruent sides. These congruent sides are called legs. The point at which these legs meet is called the vertex point of the isosceles triangle, and the angle formed by the legs is called the vertex angle. The other two angles of the triangle are called base angles. A labeled illustration of an isosceles triangle is shown below. In the past, we determined isosceles triangles by the lengths of their sides. In other words, if we saw that a triangle had two sides with equal lengths, then we classified the triangle as isosceles. There are other characteristics that mark isosceles triangles, however.
