A triangle.
A triangle is a shape that has 3 sides and 3 corners. It is a three-sided polygon, which is a plane shape bounded by three straight lines.
No, but a pentagon is a polygon. A polygon is a plane shape with 3 or more straight sides.
There is no specific name for "12 or more" sides. A 12 sided plane figure is a dodecagon. More generally, a plane figure bounded by 3 or more sides is a polygon.
A plane figure (a 2-dimensional shape) with six sides is a hexagon. A solid figure (a 3-dimensional shape) with six sides is usually a cuboid

a plane shape is a shape that can be drawn with all its points in one plan A plane shape is a 2-dimensional shape with only (X) and (Y) measurements which are height and length. A square has 4 sides and 4 corners. A circle has one never ending line and no corners. A rectangle is longer than a square. A triangle has 3 sides and 3 corners. A hexagon has 6 sides and 6 corners. Any plane shape has the same amount of corners as sides. An octagon has 8, a decagon has 10, a pentagon has 5. Because a circle's line is never ending and curves in the same direction, a circle has an infinite line of symmetry.

i have algebra and all it means is a shape with 3 sides...and 3 vertices! just like 2nd grade!
Depending on their shapes and sizes you can make plane shapes with 3 to 24 sides.
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.
No because a quadrilateral has 4 sides whereas a triangle has 3 sides.
A closed plane shape with three or more straight sides is called a polygon. The simplest polygon is a triangle, which has three sides, while other examples include quadrilaterals (four sides), pentagons (five sides), and hexagons (six sides). Polygons can be classified as regular, where all sides and angles are equal, or irregular, where they vary in length and angle.
