No.
No because in order to construct a triangle the sum of its 2 smaller sides must be greater than its longest side.
A tetrahedron is not an irregular triangle, it is a three dimensional shape, the simplest form of pyramid, with 4 triangular sides.
Yes, two sides of the triangle have to add up to more than the third side
No. The sum of any two sides of a triangle MUST be greater than the third side. 9 + 4 is 13 which is not greater than 15.
225(radical "3")/4
a triangle has 3 sides. a rectangle has 4 sides.
No.
NO!!!! A parallelogram has 4(four) sides. A Triangle has 3(three) sides.
No because in order to construct a triangle the sum of its 2 smaller sides must be greater than its longest side.
No. A triangle has 3 sides. A quadrilateral has 4 sides.
Yes.
No it is not possible because the sum of the lengths of the two sides has to be greater than the length of the third side. 5 + 4 = 9 which is less than 11, so we can't form a triangle with these sides.
Sum of any two sides of a triangle is greater than third side. 3 + 4 = 7 < 8, but 7 is less than 8. So, it is not possible to form triangle with sides of length 3, 4 and 7 units.
Because a triangle has 3 sides whereas a parallelogram has 4 sides
A tetrahedron is not an irregular triangle, it is a three dimensional shape, the simplest form of pyramid, with 4 triangular sides.
