No. In a polygon (a plane shape with sides which are straight lines), a diagonal is a line from one vertex to another provided it is not already a side of the polygon. In a triangle, the only lines which can join two vertices are sides of the triangle. Therefore they are not diagonals: that is, a triangle (right angled or not) cannot have diagonals.
1.
there is 2 diagonals in a triangle
it is a right triangle because a rhombus' diagonals are perpendicular
The only diagonal line in a right-angle triangle is the hypotenuse. So the answer is 1.
A geometrical triangle has 3 sides but no diagonals.
a triangle has three diagonals as well as three sides
A circle!! * * * * * Wrong: the diagonals of a circle DO bisect each other. A triangle is a possible answer.
0 they have no diagonals
A triangle has no diagonals
Triangles have 0 diagonals.
4 because the diagonals bisect each other at 90 degrees
The number of Diagonals in one vertex of a Triangle is 0 (zero)..
