What is a polygon with no diagonal?
The only polygon with no diagonal is the triangle.
Find the diagonal of a square whose sides are 12?
Use Pythagoras on the triangle formed by two adjacent sides and the diagonal between their other ends: diagonal = √(122 + 122) = 12 x √2 ~= 16.97 units
What is the diagonal line on a triangle called?
hypotenuse
Can You Find triangular numbers in Pascals triangle?
Yes. I think they're in the 3rd diagonal of the triangle. Basically, its how many numbers you need to make a geometrically correct triangle: 1, 3, 6, 10......
Does a triangle always have diagonal lines?
The sides of the triangle will always meet at angles such that two of them will appear 'diagonal'. But these are not defined as diagonal lines. There are actually no diagonals intersecting any triangle. Try drawing one and connecting the vertices - it doesn't work and you simply end up tracing over the lines that define the triangle.
Does a triangle have a diagonal?
No
What is a polygon with no diagonal?
The only polygon with no diagonal is the triangle.
How do you put diagonal in a sentence?
you talk about how a triangle's line is diagonal.
How do your find the diagonal measurement for a 10 ft square?
Two adjacent sides of a square and the diagonal joining their ends froms a right angle triangle. The legs of the triangle are 10 ft each and the diagonal is the hypotenuse. By pythagoras, diagonal = sqrt(102 + 102) = 10*sqrt(2) = 14.142 ft (to 3 dp).
When a square is divided by diagonal is it called an equilateral triangle?
no but the diagonal divides the square into two equilateral triangles. An equilateral triangle is a triangle that has two sides of the same length
How long is the diagonal of a rectangle with dimensions 7in by 10in?
You use the pythagorous theorm to calculate the hypotenuse of the triangle, which is the same line as the diagonal. 7(7)+ 10(10)= diagonal x diagonal 149= diagonal x diagonal Diagonal= square root of 149: this approximates to 12.207in Visit quickanswerz.com for more math help/tutoring! Consider a rectangle with dimensions 7 inches by 10 inches. Let ABCD be the rectangle. We need to find the length of the diagonal. We know that the diagonals of a rectangle are same in length. So, it is enough to find the length of the diagonal BD. From the rectangle ABCD, it is clear that the triangle BCD is a right angled triangle. So, we can find the length of the diagonal using the Pythagorean Theorem. BD2 = BC2 + DC2 BD2 = 102 + 72 BD2 = 100 + 49 BD2 = 149 BD = √149 BD = 12.207 So, the length of the diagonal is 12.21 inches.

What is the length of a diagonal rectangle with a length of 9 inches and a width of 3 inches?
To find the diagonal length of a rectangle use Pythagoras' theorem for a right angle triangle.
Use the word diagonal in a sentence?
Kitty-corner is another term for diagonal. A right triangle's hypotenuse is on a diagonal. On a keypad, the five is on a diagonal from the nine.
How is the length of a diagonal of a square found?
As a square has right angles, the diagonal forms a right triangle with two of the sides of the square. Therefore use Pythagoras: diagonal² = side² + side² → diagonal² = 2side² → diagonal = side × √2 Therefore to find the length of the diagonal of a square, multiply the side length of a square by the square root of 2.
How many diagonal lines in a triangle?
zero
What is the diagonal line on a triangle called?
