How long are each sides of an equilateral triangle if the perimeter is 60?
20. There are 3 sides to any triangle. For an equilateral triangle all 3 sides are the same length. Therefore for this triangle we can say that, where x equals the length of a side: 3x = 60 x = 60/3 x = 20
What is the length of the altitude of an equilateral triangle when sides are 20 in length?
Using Pythagoras' theorem its height works out as 17.321 inches rounded to 3 decimal places
How many 1 inch triangles are needed to make a row of triangles that has a perimeter of 20 inches?
If a "1 inch triangle" means a triangle each of whose sides is 1 inch, then there is no answer to the question. These are equilateral triangles and equilateral triangles can tesselate to form a larger equilateral triangle. The fact that the large triangle is equilateral means that its three sides are equal so that its perimeter ie the sum of the three sides must be divisible by 3. 20 is not divisible by 3.
How do you find the missing measurement on a triangle that has a base of 20 and an area of 302?
0.5*20*height = 302 Multiply both sides by 2 and then divide both sides by 20 to find its height:- height = 30.2 units of mersurement Check: 0.5*20*30.2 = 302 square units
What is the name of a 20 face shape?
An icosahedron is a regular polyhedron with 20 equilateral triangle faces.
What is the area of equilateral triangle with height is 20 and Base is 15?
An equilateral triangle with a height of 20 has a base of 23.1 (23.09401), not 15. If the base is 15 then the height will be 13 (12.99038).

A triangle has 3 sides that each equal 10cm what kind of triangle is it?
Size or internal angles?
How many sides does an icoshedron have?
20 equilateral triangular sides

What are the regulars?
The plural of "polyhedron" is "polyhedra." There are only 5 regular polyhedra:Tetrahedron, 4 sides, all equilateral trianglesCube (or hexahedron), 6 sides, all squaresOctohedron, 8 sides, all equilateral trianglesDodecahedron, 12 sides, all equilateral pentagonsIcosahedron, 20 sides, all equilateral triangles
What is the area of a rigth triangle whose sides are 25 in and 20 in respectively?
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.

Triangle abc is isosceles and has a perimeter of 20 cm sides ab and ac are each as long as bc calculate the length of the sides bc?
If ab and ac are each as long as bc then the triangle is, in fact, equilateral, not just isosceles. Therefore, each side is 20/3 cm = 6.66... recurring cm.
