An altitude is a line segment in a triangle from a vertex to the side opposite that vertex, and perpendicular to that side. So, in order to construct an altitude, first swing an arc from the vertex that is large enough to intersect the opposite side twice.
Keeping this in view, how do you find the altitude of a triangle given 3 sides?
If you know the base and area of the triangle, you can divide the base by 2, then divide that by the area to find the height. To find the height of an equilateral triangle, use the Pythagorean Theorem, a^2 + b^2 = c^2.
Beside above, is the altitude of a triangle the same as the height?
In a triangle, a line segment from a vertex and perpendicular to the opposite side is called an altitude. It is also called the height of a triangle. When a triangle is a right triangle, the altitude, or height, is the leg.
What is the Orthocenter of a triangle?
The orthocenter is the point where all three altitudes of the triangle intersect. An altitude is a line which passes through a vertex of the triangle and is perpendicular to the opposite side. There are therefore three altitudes in a triangle.
What is the altitude of a right triangle?
In geometry, an altitude of a triangle is a line segment through a vertex and perpendicular to (i.e., forming a right angle with) a line containing the base (the side opposite the vertex). This line containing the opposite side is called the extended base of the altitude.
