## Triangle
|
|
|
|
A triangle is a polygon which has three sides and vertices, whose internal angles add up to 180 degrees.
|
|
|
|
Any side of a triangle can be considered a base (B).
|
|
|
|
The distance from the base to the vertice that does not touch it is the height (H).

### Classifications
|
|
|
|
- A right triangle is a triangle that contains one angle equal to 90 degrees.
|
|
|
|
- An acute triangle is a triangle that consists entirely of angles less than 90 degrees.
|
|
|
|
- An obtuse triangle is a triangle that contains one angle more than 90 degrees.
|
|
|
|
- An equilateral triangle's 3 sides and angles are always equal in length and degree (and therefore the angles are equal to 60 degrees).
|
|
|
|
- An isosceles triangle has 2 sides and angles that are equal in length and degree.
|
|
|
|
- A scalene triangle has no sides or angles that are equal in length or degree.
