They are both shapes and an octagon can be made up of six or more triangles. Other than that they are not similar. A triangle must have three sides. An octagon must have eight sides.
The angles for congruent shapes and the angles in similar shapes are all the same. All the sides are also proportional in both. Basically, all congruent shapes are similar but not all similar shapes are congruent.
anything smaller than the triangle
equilateral triangle, isosceles triangle, and theres more but i forgot.
Because triangle are shapes too
Similar shapes.
