# What is the orthocenter of a right triangle?

The orthocenter is defined as the point where the altitudes of a right triangle's three inner angles meet. It is also the vertex of the right angle.

Continue ReadingSince two of the sides of a right triangle already sit at right angles to one another, the orthocenter of the right triangle is where those two sides intersect the form a right angle. The altitude of the third angle, the one opposite the hypotenuse, runs through the same intersection point. The orthocenter of an obtuse triangle lays outside the perimeter of the triangle, while the orthocenter of an acute triangle lays inside the triangle.

Q:
## Does a triangle have parallel sides ?

A: A triangle can never have any parallel lines because there must be three angles that add up to 180 degrees, which makes it impossible for the three sides t... Full Answer >Filed Under: -
