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.
Then it is a scalene triangle
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.
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.
A decagon has 7 more sides than a triangle. A triangle has 3 and a decagon has 10.
