How many diagonals can be drawn from one vertex of a polygon of 50 sides?
47 sides. Take a vertex of an n-sided polygon. There are n-1 other vertices. It is already joined to its 2 neighbours, leaving n-3 other vertices not connected to it. Thus n-3 diagonals can be drawn in from each vertex. For n=50, n-3 = 50-3 = 47 diagonals can be drawn from each vertex. The total number of diagonals in an n-sided polygon would imply n-3 diagonals from each of the n vertices giving n(n-3). However, the diagonal from vertex A to C would be counted twice, once for vertex A and again for vertex C, thus there are half this number of diagonals, namely: number of diagonals in an n-sided polygon = n(n-3)/2.
What is the name of half a pentagon?
hexagon
What is the hexagon folded in haif?
A regular hexagon folded in half would look like an isosceles trapezoid.
What is the length of one side a hexagon?
The length of on side of an equilateral hexagon is half the diameter of the circumscribing circle.
How do you find the sides of a rhombus if diagagonal are given?
The diagonals bisect each other at right angles. So you could use Pythagoras on half the diagonals. So, if the diagonals are a and b units long, then half the diagonals are a/2 and b/2 units long. Then, by Pythagoras, the sides of the rhombus are sqrt[(a/2)2 + (b/2)2]
How many diagonals can be drawn to divide the square in half?
A square has only to diagonals and either one will divide it in half.
How diagonals are there in a hundred corner shape?
Each diagonal runs from one corner of the shape to an opposite corner, so each diagonal requires 2 corners. So in a hundred cornered shape there will be half of a hundred diagonals, which is 50. Just divide the number of corners by 2. So for a hexagon, which has 6 sides and 6 corners, there are 3 diagonals.
How many pairs of triangles are formed if a rectangle is divided into half and diagonals are drawn?
Probably 6 if not 4 if not 8 if not 10.WHO CARES
What is half a hexagon?
Half of a hexagon is a trapezoid.
Can you divide a hexagon into 2 congruent pentagons?
Yes - divide the hexagon by drawing a line connecting two opposite sides, dividing it in half. (Drawing a line connecting two angles will only result in two congruent quadrilaterals).
Prove that a rhombus has congruent diagonals?
Since the diagonals of a rhombus are perpendicular between them, then in one forth part of the rhombus they form a right triangle where hypotenuse is the side of the rhombus, the base and the height are one half part of its diagonals. Let's take a look at this right triangle.The base and the height lengths could be congruent if and only if the angles opposite to them have a measure of 45⁰, which is impossible to a rhombus because these angles have different measures as they are one half of the two adjacent angles of the rhombus (the diagonals of a rhombus bisect the vertex angles from where they are drawn), which also have different measures (their sum is 180⁰ ).Therefore, the diagonals of a rhombus are not congruent as their one half are not (the diagonals of a rhombus bisect each other).
How many diagonals can be drawn from one vertex of a polygon of 50 sides?
47 sides. Take a vertex of an n-sided polygon. There are n-1 other vertices. It is already joined to its 2 neighbours, leaving n-3 other vertices not connected to it. Thus n-3 diagonals can be drawn in from each vertex. For n=50, n-3 = 50-3 = 47 diagonals can be drawn from each vertex. The total number of diagonals in an n-sided polygon would imply n-3 diagonals from each of the n vertices giving n(n-3). However, the diagonal from vertex A to C would be counted twice, once for vertex A and again for vertex C, thus there are half this number of diagonals, namely: number of diagonals in an n-sided polygon = n(n-3)/2.
How do you calculate the surface area of a hexagon?
measure 1 (S) side of the hexagon, write it down, measure across from corner to another in a straight line, divide it in half (R) multiply S by R and multiply by 3, youll have your answer
What fraction of a hexagon is the trapazoid?
A half. ½
What is the name of half a pentagon?
hexagon
How can you use triangles to figure out the area of a hextagon?
If you Google "area of a hexagon," you'll find quite a few websites with illustrations that will explain this better than I can without them. If you draw three diagonals from opposite corners of the hexagon, you will notice that the hexagon has been divided into six equilateral triangles. If you then draw six lines from the center to the midpoint of each side, you will have created twelve equal right triangles and can find the area of each by taking half of the base (which is half of a side) times the height. Multiply that by 12 and you have the area of the hexagon. The height of each triangle is the line you drew from the center to the middle of the side. This is known as an "apothem."
What is 2 hexagons and one-half of a hexagon equal a fraction?
2 hexagons and 1 half hexagon, equals 2.5 as a fraction (in decimal form).
