Classifications by side length or comparison of angles and sides:

scalene - no sides or angles equal

isosceles - two sides and angles equal (congruent)

equilateral - all sides and angles equal (all 60° angles)

Classifications by included angles :

right triangle - contains a 90° angle (right angle)

oblique triangle - has no right angle

acute triangle - contains all angles less than 90°

obtuse triangle - contains one angle greater than 90°

An octogon contains 6 equilateral triangles.

scalene triangles

6-2 = 4 triangles

8-2 = 6 triangles

Because all other polygons are made from triangles as for example an 8 sided octagon has 6 triangles within it or a 6 sided hexagon has 4 triangles within it.

An octogon contains 6 equilateral triangles.

There are six triangles in an octagon. In any convex polygon, there are two less triangles than the number of sides. So a octagon which has 8 sides, contains 6 triangles.

Acute, equilateral, isosceles, obtuse, right angle, scalene are all names of different types of triangles.
