They will form a 4 sided quadrilateral if the triangles are the same sizes.
Absolutely. Any two congruent right triangles will form a rectangle, and if the right triangles are isosceles right triangles, they will form a square.
A pair of triangles can form a 4 sided quadrilateral
Triangles do not have parallel lines but as right angles triangles they do have perpendicular lines that meet at 90 degrees.
To create five triangles from the four triangles formed by nine matchsticks, you can move two matchsticks from one of the triangles to create a new triangle. Specifically, remove one matchstick from the base of one triangle and one from the apex of an adjacent triangle, and reposition them to form an additional triangle that shares sides with the existing triangles. This reconfiguration will yield a total of five triangles.
It can form 7 triangles
They will form a 4 sided quadrilateral if the triangles are the same sizes.
If it is in the form of two inverted triangles, then there are 8 triangles. If only the outline is used, there are 0 triangles.
