Yes, because the sum of its smaller sides is greater than its longest side.
that's not a triangle
12, 7, 7
Yes and it will be an isosceles triangle with 2 equal sides
This is a scalene triangle as it has no equal sides or angles. It is not a right angle triangle.
That would be an isosceles triangle if two sides are the same length.
that's not a triangle
12, 7, 7
A triangle with side a: 7, side b: 12, and side c: 11 units has an area of 37.95 square units.
Yes and it will be an isosceles triangle with 2 equal sides
An heptagon has 7 sides and a triangle has 3 sides
This is a scalene triangle as it has no equal sides or angles. It is not a right angle triangle.
That would be an isosceles triangle if two sides are the same length.
Those segments can form a triangle because the two smallest sides, 7 and 8, add together to make 15, which is greater than the longest side, 12.
Then it is a scalene triangle
Scalene
The perimeter of a triangle is the sum of the lengths of its sides. In this case, the perimeter of the triangle with sides measuring 3 inches, 5 inches, and 7 inches is 3 + 5 + 7 = 15 inches.
The triangle with side lengths of 6, 7, and 8 is classified as a scalene triangle because all three sides have different lengths. Additionally, it is not a right triangle, as the square of the longest side (8) is not equal to the sum of the squares of the other two sides (6 and 7). Thus, it is simply a scalene triangle.
