What shapes will have diagonals that are not lines of symmetry
Answers

how many triangles are formed by the diagonal from one vertex in quadrilateral, hexagon, octagon, and decagon??!
Answers
Quadrilateral: two (you can only trace one diagonal and it forms two triangles)
Hexagon: four (you can trace thre diagonals and four triangles are formed)
Octagon: six (you can trace five diagonals and six triangles are formed)
Degagon: eight (you can trace seven diagonals and eight triangles are formed)
It is always true that the number of triangles you can form from a vertex in a convex polygon is the number of sides minus 2.
