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 triangle as no other 2d shape can have 3 sides.
