All plane figures that have 3 sides are triangles (tri means 3). There are different triangles based on if all 3 sides are the same length, 2 sides the same, or none. If none are the same lengths, that Is a scalene triangle.
A three sided closed plane figure (shape) is a triangle.
A Scalene Triangle
A plane figure cannot be bounded by only one straight line. If the shape is bounded by lines which are not straight or by several straight lines the answer will depend on exactly what these are.
N-gon for a closed plane figure bounded by straight line segments as sides, or otherwise try just "Shape"
it is a plane shape because you said its a square

quadrilateral
A three sided closed plane figure (shape) is a triangle.
irregular quadrilateral
A rectangle. Think about it.
A trapezoid is a 4 sided shape that has one pair of parallel sides of different lenghts
A flat shape.
A plane figure is a geometric shape. A plane figure is known as a 2-dimensional shape because it has only length and breadth. The thickness of the plane figure is zero. Any shape that is drawn on paper is known as a plane figure. In the real world, there is no object that represents a plane figure.

A twelve-sided plane figure is called a dodecagon.
a solid figure with five plane surfaces
