A 30-60-90 right triangle
Right Triangles
Equilateral triangles.
The orthocenter of a triangle is the point where the three altitudes intersect. It can be located inside the triangle for acute triangles, on the triangle for right triangles, and outside for obtuse triangles. The orthocenter is one of the triangle's key points of concurrency, along with the centroid and circumcenter. Its position varies depending on the type of triangle being considered.
Equilateral triangles have rotational symmetry.
A 30-60-90 right triangle
A parallelogram can be split into two congruent triangles known as "parallelogram halves" or "diagonally opposite triangles." These triangles share a common base, which is half the length of the parallelogram's diagonal. The height of each triangle is the perpendicular distance between the base and the opposite side of the parallelogram.
That will depend on what type of triangle it is as for example if it is an isosceles triangle then it will form two congruent right angle triangles.
it is a right triangle because a rhombus' diagonals are perpendicular
