Yes, a triangle is a "flat" figure. A triangle is three distinct points connected by line segments, and it takes three points to determine a plane. That translates to the fact that a triangle is a planar figure; it lies on a plane.
An easy way to see this is to take a string and tie the ends to any two points (like two table legs). Then pick up the string in the middle. The two ends and your fingers represent the three points of the triangle. No matter where you move your hand, the triangle will remain a flat figure.
Of course, if you draw a triangle on a sphere or other curved surface, the sides will be arcs, not straight lines.
its self because a plane figure is a figure that is flat and has all strait sides.
It is a figure that is flat. For example: triangle, square, pentagon...ect. A three dimensional figure is like a sculpture. Example: pyramid, cube prism...etc.
No- a triangle is a plane figure, not a solid.
square based pyramid is made up of four triangle and a flat square base and it is a solid figure
No. A triangle is a two-dimensional figure. It has only length and width, but not thickness. It's a flat shape that can be drawn on a piece of paper, whereas solids are 3-dimensional (for example, a pyramid).
A flat three sided figure is a triangle.
Yes it is 2 D
its self because a plane figure is a figure that is flat and has all strait sides.
The face of a triangle is the flat surface of the solid figure. _________________________________________________ A face is a side of a 3 dimensional figure. So, the number of faces a triangle would be 0.
A tetrahedron is a solid figure with four flat surfaces that are triangles. Each face of a tetrahedron is a triangle, making a total of four triangular faces in the shape.
It is a figure that is flat. For example: triangle, square, pentagon...ect. A three dimensional figure is like a sculpture. Example: pyramid, cube prism...etc.
yes, a triangle is a closed figure
No- a triangle is a plane figure, not a solid.
A flat figure polygon is a 2-D figure. It can be a square rectangle decagon dodecagon nonagon heptagon hexagon triangle parallelogram rhombus trapezoid and I forgot what the 2-D name for an 11 sided figure. (2-D can only be shown on paper and a polygon is any CLOSED figure) Hope this Helps!!! A.S.
A polygon is any flat figure having three or more sides. For example - triangle, square, pentagon, hexagon, septagon...
square based pyramid is made up of four triangle and a flat square base and it is a solid figure
