A Plane triangle cannot have parallel sides.
A triangle on a sphere, represented in Mercator projection may do so, but that still does not make it so, for that is in spherical geometry.
And there are other geometries than Euclidean (plane).
Hyperbolic Geometry and Elliptic Geometry are the names of another two.
These geometries are consistent within themselves, but some of the theorems in Euclidean geometry have different answers in these alternate geometries.
Triangles actually do not have any parallel sides.
Yes
i think it is a trapezium.....
No.
How do you draw a quadrangle with no parellel sides?
parrellogram
trapezoid :)
No
Scalene Triangle: a triangle with no two sides equalIsosceles Triangle: a triangle with two sides equalEquilateral Triangle: a triangle with all sides equalRight Triangle: A triangle with two 'legs' vertex creates a 90o angle.
A triangle with two congruent sides is an isosceles triangle, and a triangle with three congruent sides is an equilateral triangle.
rhombus
A triangle which has no two sides congruent is called a Scalene Triangle.
