TRIANGLE AND ITS PROPERTIES
![Page 2: Triangles and its properties](https://reader034.vdocuments.us/reader034/viewer/2022042716/55a6608b1a28ab5b538b4681/html5/thumbnails/2.jpg)
The vertex (plural: vertices) is a corner of the triangle. Every triangle has three vertices.

The base of a triangle can be any one of the three sides, usually the one drawn
at the bottom.

The altitude of a triangle is the perpendicular from the base to the opposite vertex. (The base may need to be extended).
Since there are three possible bases, there are also three possible altitudes. The three altitudes intersect at a single point, called
the orthocenter of the triangle.

The median of a triangle is a line from a vertex to the midpoint of the opposite side. The three medians intersect at a single point, called the centroid of the
triangle.

The three angles on the inside of the triangle at each vertex.

The angle between a side of a triangle and the extension of an
adjacent side.

A triangle where one of its interior angles is a right angle (90 degrees).

A triangle where one of the internal angles is obtuse
(greater than 90 degrees).

A triangle where all three internal angles are acute (less than 90
degrees).

A triangle which has all three interior angles equal (congruent).

A method for calculating the area of a triangle when you know the
lengths of all three sides.
