 # Is Altitude Always 90 Degree?

## Which is the longest side of a right triangle?

hypotenuseThe hypotenuse of a right triangle is always the side opposite the right angle.

It is the longest side in a right triangle.

The other two sides are called the opposite and adjacent sides..

## Is altitude a height?

As a general definition, altitude is a distance measurement, usually in the vertical or “up” direction, between a reference datum and a point or object. … Although the term altitude is commonly used to mean the height above sea level of a location, in geography the term elevation is often preferred for this usage.

## Do altitudes make right angles?

Altitudes are perpendicular and form right angles. They may, or may NOT, bisect the side to which they are drawn. Like the medians, the altitudes are also concurrent. When drawn, the lines containing the three altitudes will intersect in one common point, either inside, on, or outside the triangle.

## Does altitude make 90 degrees?

In geometry, the altitude is a line that passes through two very specific points on a triangle: a vertex, or corner of a triangle, and its opposite side at a right, or 90-degree, angle. … It also forms a right angle as it crosses the opposite side, which is called the base.

## What are the properties of an altitude?

Properties of Altitudes of a Triangle The altitude is the shortest distance from the vertex to its opposite side. The 3 altitudes always meet at a single point, no matter what the shape of the triangle is. The point where the 3 altitudes meet is called the ortho-centre of the triangle.
