What is the number of sides in one equilateral triangle one right angle triangle one isoceles triangle and two scalene triangles?
1 triangle = 3 sides, no matter what kind of triangle it is 5 triangles = 3 sides each = 15 sides
Can a triangle have sides equal to 7 inches 8 inches and 15 inches?
yes, some sides would have different measurements
If a triangle has two sides that are 15 inches each and the third side measures 10 inches what kind of triangle is it?
This would be an isosceles triangle.
Is a triangle with sides of 8m 17m 15m a right triangle why or why not?
If it were, then 17 squared would equal 8 squared plus 15 squared. ie 289 would equal 64 + 225 which it does, so it is a pythagorean triangle.
A triangle with sides of lengths 12 15 and 20 is a right triangle?
False. It can't be.In a right triangle, the sum of the squares of the two short sides is equal to the squareof the longest side.122 = 144152 = 225-------------sum = 369202 = 400, not 369.So these are not the sides of a right triangle.

What kind of triangle has two sides with length 15 and one side with length 25?
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.

Does equilateral triangle with sides of length 5 has the same perimeter as an isosceles triangle with the base of length 3 and two equal sides of 6?
Yes 5+5+5 = 15 6+6+3 = 15
Dwayne's garden is triangle-shaped with two equal sides and a third side that is 4 ft more than the length of an equal side If the perimeter is 49 ft how long is each side?
Call the two equal sides 2x and the third side x+4: 2x+x+4 = 49 2x+x = 49-4 3x = 45 x = 15 So the length of two equal sides are 15 ft each and the larger side is 19 ft (Incidentally the garden is in the shape of an isosceles triangle)

Is A triangle with sides of lengths 12 15 and 20 a right triangle?
No. Pythagoras' theorem states that when the square of the hypotenuse is equal to the sum of the squares of the other two sides then it is a right-angled triangle. The hypotenuse is the longest side (opposite the supposed right angle). In this case the hypotenuse is 20. The square of 20 is 400. The other two sides are 12 and 15. The square of 12 is 144 and the square of 15 is 225. The sum is therefore 225 + 144 = 369, which is not equal to 400, therefore the triangle cannot be a right-angled triangle.

Triangle with sides 7 12 15?
that's not a triangle
What is the length of a hypotenuse with the right triangle sides 15 and 36?
The length of a hypotenuse with the right triangle sides of 15 and 36 is: 39
What is the area of a triangle with sides of 36 39 and 15?
It is a right angle triangle with an hypotenuse of 39 and sides of 36 and 15. Area of triangle is 0.5*36*15 = 270 square units
