Say you divide a pentagon into some equal triangles. What kind of triangles would they make? 30-60-90, equilateral blahblahblah..?
-
isosceles- angles would be 72 at center an two 54 angles on edges to make 5 triangles altogether
-
If they have all the same length sides and angles, its an Equilateral triangle.
Isosceles triangles have 2 sides the same, and one side longer.
Scalene triangles have no sides the same length.
It would most likely be an Isosceles triangle though.

I'd draw a dot in the center of the pentagon and draw lines to the vertices. This would produce five isosceles triangles with angles of 72, 54, and 54 degrees.

540 degrees total interior angle sum
540/5 = 108 per angle
108, 36, 36 isosceles triangles
540/5 = 108 per angle
108, 36, 36 isosceles triangles

Isosceles triangles, assuming the pentagon is regular.
