Question

triangal have any dioganal​

Answer 1

Answer:

Triangles do not have any diagonal because in triangle, no non-adjacent vertices are found.

Answer 2

Answer:

No, It has no diagonals.

Step-by-step explanation:

A diagonal of a polygon is a line from a vertex to a non-adjacent vertex. So a triangle, the simplest polygon, has no diagonals. You cannot draw a line from one interior angle to any other interior angle that is not also a side of the triangle.

Simply you try to join opposite vertexes of triangle. You can't??? Even noone can do so.

So, we can say no.
