Can u make a triangle with 5 matchsticks?

If you cannot make a triangle, think of reasons for it. This is a square, hence with four matchsticks, we cannot make triangle. (c) 5 matchsticks. This is an acute angle triangle and it is possible to make a triangle with five matchsticks, in this case, sum of two sides is greater than third side.

What is the maximum number of equilateral triangles with 5 matchstick?

One can arrange five match sticks to simultaneously represent two equilateral triangles, sharing one side. One can sequentially rearrange five matchsticks on a plane to form 20 unique equilateral triangles.

How many triangles can 6 matchsticks make?

4 equilateral triangles

Does 4 8 12 make triangles?

The sum of 4 and 8 is 12 and 12 is less than 15 . This set of side lengths does not satisfy Triangle Inequality Theorem. These lengths do not form a triangle.

Can a triangle be 5 5 10 sides?

Can any three lengths make a triangle? The answer is no. The Triangle Inequality Theorem states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third.

What is a triangle with 5 sides?

In geometry, a pentahedron (plural: pentahedra) is a polyhedron with five faces or sides.

Can a Pentagon be split into 5 equilateral triangles?

If we divide a pentagon into triangles as in the figure on the left below, the pentagon is made up of 3 triangles, so the angle sum is 180 + 180 + 180 = 3*180 = 540 degrees. However, the non-convex pentagon on the right is a trickier case….Angles in Isosceles Triangles.
