an obtuse, scalene triangle
The perimeter of any triangle is the sum of its 3 sides
It is an isosceles triangle if 2 sides measure 25 feet and the other side measures 10 feet
It is: 0.5*25*20 = 250 square inches It doesn't matter whether or not a triangle is a right triangle; the area is always half of the base times the height.
When a triangle has no angles =to 90 degrees, it is called an oblique triangle.When one of the angles of an oblique triangle is greater than 90 degrees, it can also be called an obtuse triangle.Technically, the triangle described would also be a type of scalene triangle, although we should only call it this when it is defined by the length of its sides, rather than by its internal angles.
The Pythagorean theorem states that the length of the hypotenuse of a right triangle is the square root of the sum of the squares of the other two sides.[(24 in)^2 + (7 in)^2]^(1/2) = 25 in
It is a scalene triangle that fits the given dinmensions
The perimeter of any triangle is the sum of its 3 sides
No because the sides don't comply with Pythagoras' theorem for a right angle triangle.

isoscelesAs regard their sides, triangles may beScaleneIsoscelesEquilateralAnd in regard to their angles, triangles may beAcuteRightObtuseEquiangularA triangle is scalene if all of its three sides are 'different'.If only two of its sides are equal, the triangle is called isosceles.A triangle with all three 'equal' sides is called equilateral.So, a triangle with a length of 15 on two sides and a length of 25 on the third side would be Isosceles, since two of the sides are the same.
There are six sides in a hexagon, five in a pentagon, and three in a triangle. So in 2 hexagons, 2 pentagons, and 1 triangle there are 2*6 + 2*5 + 1*3 = 12 + 10 + 3 = 25 sides altogether.
A scalene triangle
Because the sum of the squares of the smaller sides equals the square of the largest side: 32+42 = 25 and 52 = 25
a scalene triangle is a triangle with three differant sides
You need THREE sides for a triangle. Once you have them, you can check with the Pythagorean theorem whether it is a right triangle: the square of the longest side must be equal to the sum of the squares of the other two sides.
Triangle inequality says that the sum of the lengths of any two sides of a triangle is greater than the length of the third side.Since 15 + 5 = 20 < 25, we cannot draw a triangle.
Perimeter = 3*25 = 75 cm
