Can all 4 sided figures be made from triangle? why?
No. A triangle has only three sides.
Yes. You can take a four sided shape and have a line go through one corner to the opposite. that would be two triangles making up a four sided shape.
i agree jimm
No, not all four-sided figures can be formed from triangles. A triangle is a polygon with three sides and three angles. It is not possible to construct a four-sided figure solely from triangles because it would require at least two triangles to be connected, resulting in more than four sides.
However, some four-sided figures can be decomposed or split into triangles. For example, a square can be divided into two congruent triangles by drawing a diagonal from one vertex to the opposite vertex. Similarly, a rectangle can be divided into two congruent right triangles by drawing a diagonal.
In general, any convex quadrilateral (a four-sided figure with all interior angles less than 180 degrees) can be decomposed into two triangles. This can be done by drawing one of the diagonals of the quadrilateral.
On the other hand, concave quadrilaterals (a four-sided figure with at least one interior angle greater than 180 degrees) cannot be decomposed into triangles without extending the figure or adding additional lines.
