How many diagonals from one vertex in 16gon?
Using the formula 0.5(n^2 -3n) whereas n is number of sides, altogether there are 104 diagonals in a 16 sided polygon
In a right triangle Is the hypotenuse always the longest of the three sides?
Yes, because the sides connected to the right angle cannot extend longer than the distance between their end points.
Are diagonals equal to side lengths of rectangles?
No. A diagonal goes from corner to opposite corner, which will always be a longer distance than the side length. You can use Pythagoras' theorem to work out the length of the diagonals. It will be the square root of (a2+b2) where a and b are the long and short side lengths of the rectangle respectively. The result will clearly be greater than either a or b.
Can a right angle triangle ever be equilateral?
No it can't. The hypotenuse of a right triangle will always be longer than either one of the other two sides.
How many diagonals does a dodecagon have?
12. There is actually a better answer and much larger answer than 12. The real answer is 54. Just because a dodecagon has 12 sides doesn't mean it has 12 diagonals because you can go either which way. To get a answer for this you can: 1. Multiply 12 and 9. You should get 108. 2. Then divid it by 2. You should get 54. That is correct: The general rule for a polygon with n sides is that it has n*(n-3)/2 diagonals.
What polygons are all the diagonals always longer than the sides?
squares,rectangles,regular pentagons
Are diagonals in regular pentagons and regular hexagons always longer than the length of the sides?
yes
Are the diagonals of a kite longer than the sides?
Do this question yourself
Are both diagonals of any parallelogram longer than the sides?
Yes.
How do you know if your solving for the leg or the hypotenuse?
The hypotenuse will always be longer than the other sides.
Which shapes have more than two diagonals?
Any polygon with more than 4 sides.
Does a rhombus have parallel sides and equal diagonals?
Opposite sides are equal and parallel but diagonals are only equal in certain specific circumstances eg when all angles are equal, which makes it a square rather than a rhombus.
How many diagonals from one vertex in 16gon?
Using the formula 0.5(n^2 -3n) whereas n is number of sides, altogether there are 104 diagonals in a 16 sided polygon
Does a square have two pairs of opposite sides parallel?
yes. a square always has four equal sides. a rectangle also has four sides but one set is longer than the other.
What forms within a polygon shape?
Interior angles and if it has more than 3 sides also diagonals
Do the two opposite sides of a rectangle have to be longer than the other two opposite sides?
Usually when thinking of a rectangle we see that two parallel sides are longer than the other two. However a rectangle is just defined as having four right angles so a square can be a rectangle meaning that a rectangle may have all four sides of the same length. A square is always a rectangle. A rectangle is not always a square.
Are the diaganols of a square longer or shorter than its sides?
longer
