If you have 9 balls you have to make them in to a triangle with four balls on each side How do you order them with numbers from 1-9 to get each side equal the same sum?

What numbers make a triangle?
Any three numbers where the sum of the two smaller numbers is greater than the third number. List the numbers in order from least to greatest, repeating any number if necessary. Add the first two numbers together and if this sum is greater than the third number then a triangle with those sides can be made. ie if the sum of the two smaller numbers is greater than the third number then a triangle can be made.
How do you order rational and irrational numbers?
Write them as decimals, and compare. If the first digit of two numbers is equal, compare the second digit; if the second digit is equal, compare the third digit, etc.
What type of triangle must you have in order to use the Pythagorean Theorem?
A right triangle.
In order to inscribe a circle in a triangle the circles center must be placed at the circumcenter of the triangle?
No.
What is Asa for congruence?
If a side and two angles at either end of it (Angle-Side-Angle = ASA) of one triangle are the same measure as that of another triangle, then the two triangles are congruent. In fact, it does not have to be the angles at the ends of the sides in question since two angles being equal means that the third pair of angle will also be equal. So as long as the ASA are in corresponding order, the triangles will be congruent.
What are similar triangles?
Triangles that are the same shape but not the same size. In order to be a similar triangle, their numbers have to form proportions with the numbers of the similar triangle.
How much rotational symmetry does triangle have?
It depends on the type of triangle. A scalene triangle (no equal sides) has no rotational symmetry. An isosceles triangle (2 equal sides) has rotational symmetry order 2. An equilateral triangle (3 equal sides) has rotational symmetry order 3. The order of rotational symmetry is how many time a shape will fit over itself during one complete rotation.
What must be true of the side lengths in order to build a triangle with three angles measuring 60 degrees what kind of triangle is this?
In a triangle, if all of the angles are 60 degrees, then all three sides of the triangle are equal to each other. Basically, if the angles are equal than the sides must be equal. This kind of triangle is called an equilateral triangle.
Does an equilateral triangle have line symmetry?
In order to have any lines of symmetry, a triangle must have either two sides equal (isosceles) or three sides equal (equilateral).
What order of operations equal 29?
With the appropriate set of numbers, any order can be used.
Is it equal 20x20x40cm equals 40x20x20cm?
Yes. When multiplying it does not matter what order the numbers are in, it will always equal the same.
If you have 9 balls you have to make them in to a triangle with four balls on each side How do you order them with numbers from 1-9 to get each side equals 19?
1, 5, 9, 4 down the left side. 1, 3, 8, 7 down the right side. 4, 2, 6, 7 across the bottom. Other combinations are possible.
True or false A triangle with sides of lengths 10 24 and 27 is a right triangle?
false In order for this to be a right triangle, the sum of the squares of the two shorter sides would have to equal the square of the longest side. 102=100 242= 576 272=729 102+242= 676, which does not equal 272=729, so a triangle with these lengths is not a right triangle.
Math triangle sums stumper all sides equal 30 using odd numbers 1to 17 using only once each?
The only way this works is if each side of the triangle has 4 numbers - with just 3 numbers you don't get to 30. A solution is to have the numbers 1, 3 , & 5 at the vertices with the sides containing: 1, 9, 17, 3 (or 1, 17, 9, 3 - the order of the two internal numbers doesn't matter) 3, 7, 15, 5 (or 3, 15, 17, 5 - the order of the two internal numbers doesn't matter) 5, 11, 13, 1 (or 5, 13, 11, 1 - the order of the two internal numbers doesn't matter)
Are congruent triangles similar?
Yes, similar triangles are congruent because in order to be congruent they must first be equal. Which in turn is the definition of a similar triangle. A triangle equal in angle measurements and/or side lengths. So, yes.
What numbers make a triangle?
Any three numbers where the sum of the two smaller numbers is greater than the third number. List the numbers in order from least to greatest, repeating any number if necessary. Add the first two numbers together and if this sum is greater than the third number then a triangle with those sides can be made. ie if the sum of the two smaller numbers is greater than the third number then a triangle can be made.
What are the big numbers called on the periodic table?
The big numbers are atomic numbers. They are equal to number of protons. Elements are arranged in order of increasing atomic number.
