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.
What is a sentence for equilateral?
Euclid knew how to draw equilateral triangles, squares, regular pentagons and regular hexagons, and infinitely many others.Onigiri are made of cooked Japanese rice, usually pressed into an equilateral triangle about three inches across and one inch thick.The unfinished house, which is built to resemble an equilateral triangle and fashioned out of concrete and stone, is taking so long to build, he said.
What is the perimeter of an equilateral triangle of 1 inch?
It is: 3*1 = 3 inches
What is the cross sectional area of an equilateral 1 inch triangle?
An equilateral 1 inch triangle is a plane figure and it does not have a cross-sectional area in any meaningful sense, just an area. Its area is 0.43 = sqrt(3)/4 square inches.
How many triangles can you draw with the side lengths 3 inches 4 inches and 1 inch?
None because in order to draw a triangle the sum of its smaller sides must be greater than its largest side.
Are 2 equilateral triangles always congruent?
No. A triangle with 2-inch sides is not congruent with a triangle with 3-inch sides.

HOW DO YOu classify triangles based on the side lengths?
Triangles are not classified by the length of their sides, but by their shapes. A right triangle, for example, is a triangle which includes one 90o angle. This is true regardless of the size of the triangle; it could have sides a thousand miles long or a thousandth of an inch long and still be a right triangle, as long as it has that 90o angle. An equilateral triangle has three sides which are all of the same length. This is true, again, regardless of the size of the triangle. The three sides could all be a million miles long, or they could be microscopic, but if they are all the same length, then the triangle is equilateral.It would be better to ask about classifying triangles by the relative lengths of their sides.If all the sides are different lengths, we class it as a Scalene Triangle. (Note that all three angles also are different.)If exactly two sides have the same length we call it an Isosceles triangle (Note that two of the angles also are the same size. And try to get the spelling right!!!)If all three sides are the same length, we call it an Equilateral triangle. (If you like you could say that it is a special case of an isosceles triangle). All three angle are the same and they always are sixty degrees each.

Area of an equilateral triangle with a 9 inch perimeter?
3.897 square inches.
What is the perimeter of an equilateral triangle of 1 inch?
It is: 3*1 = 3 inches
What is the perimeter of an equilateral triangle that measures 4 inch on one side?
12 inches
What is the cross sectional area of an equilateral 1 inch triangle?
An equilateral 1 inch triangle is a plane figure and it does not have a cross-sectional area in any meaningful sense, just an area. Its area is 0.43 = sqrt(3)/4 square inches.
What is the Hypotenuse of a 90 degree triangle with two nine inch sides?
The hypotenuse of a 90-degree triangle with two nine inch sides is: 12.73 inches.
What is the lenghth of ea side of a hexagon if it is 20 in. from flat to flat?
Since the "slices" of an equilateral hexagon are equilateral triangles, the Pythagorean theorem will solve this problem: A squared plus B squared equals C squared, where A and B are the sides at right angle to each other and C is the hypoteneuse (long side). Slice a 10 inch tall equilateral triangle down the middle. The height A is 10 inches; the base B (1/2 of A) is 5 inches. 10 squared equals 100; 5 squared equals 25. Therefore, the length of each side of the equilateral triangle is the square root of 125, or approximately 11.18 inches. This is also the length of the sides of the hexagon in question.
What is the area rounded to the nearest tenth of a square inch of an equilateral triangle that has a perimeter of 24 inches?
Area of equilateral triangle: 0.5*8*8*sin(60 degrees) = 27.7 square inches rounded
Explain Why the height of a triangle depends on which side you select for the base?
The height of a triangle is the length of the perpendicular dropped to the base (extended if necessary) from the opposite vertex. This depends on which side is the base, unless the triangle is equilateral. For example, if you have a tall skinny isosceles triangle whose equal sides are a mile long and the third side is an inch long, the height is about a mile if you choose the third side as the base. If you choose either of the other two sides as base, the height will be about an inch.
