What else can I help you with?
A closed polygon has 14 diagonals. how many numbers of sides does it have?
It will have 7 sides
How many diagonals does a shape with 5 sides have?
5(5-3)/2. That it is the formula so that shape would have 5 diagonals. n(n-3)/2 where n is the number of sides
Is it possible for a polygon to have 83 diagonals?
If a polygon had 166 sides it would have 83 diagonals as each diagonal must join two vertices.
What is the total number of diagonals in a 35 sided polygon?
The formula is: 0.5*(n2-3n) whereas n is the number of sides So: 0.5*(352-105) = 560 diagonals
How many diagonals are in a 9 sided polygon?
The formula is: 0.5*(n2-3n) where n is the number of sides of the polygon. So: 0.5*(81-27) = 27 diagonals
What figures have parallel diagonals?
Regular polygons with even sides if there are 6 or more of them; selected irregular polygons with seven or more odd numbers of sides.
Are diagonals in regular pentagons and regular hexagons always longer than the length of the sides?
yes
How many diagonals does a polygon with 32 sides have?
It has 464 diagonals. I used n(n-3)/2. Works for all polygons.
What are the mathematical names of the first ten polygons and their properties?
All polygons have 3 or more sides having exterior angles that add up to 360 degrees and the first 10 can be classed as follows in order of their geometrical names, number of sides, sum of interior angles and number of diagonals:- 1 Triangle: 3 sides, 180 degrees and no diagonals 2 Quadrilateral: 4 sides, 360 degrees and 2 diagonals 3 Pentagon: 5 sides, 540 degrees and 5 diagonals 4 Hexagon: 6 sides, 720 degrees and 9 diagonals 5 Heptagon or Septagon: 7 sides, 900 degrees and 14 diagonals 6 Octagon: 8 sides, 1080 degrees and 20 diagonals 7 Nonagon: 9 sides, 1260 degrees and 27 diagonals 8 Decagon: 10 sides, 1440 degrees and 35 diagonals 9 Undecagon: 11 sides, 1620 degrees and 44 diagonals 10 Dodecagon: 12 sides, 1800 degrees and 54 diagonals Note that all polygons can be regular, irregular, congruent or similar
In a rectangle will the diagonals always bisect opposite sides?
Diagonals never bisect sides. They join the ends of sides.In a rectangle, the diagonals always bisect each other.
What shape has equal diagonals that bisect each other but no other information is known?
All regular polygons with an even number of sides. Also rectangles.All regular polygons with an even number of sides. Also rectangles.All regular polygons with an even number of sides. Also rectangles.All regular polygons with an even number of sides. Also rectangles.
Are the diagonals of a rhombus sometimes perpendicular?
A rhombus has 4 equal sides and the diagonals are always perpendicular
Are the diagonals of a kite longer than the sides?
Do this question yourself
Do regular polygons always have equal length sides?
yae they always do:)
What polygons always have congruent sides?
squares and triangles :/
Are the diagonals of a trapezoid always congruent?
No, the diagonals of a trapezoid are not always congruent. A trapezoid is a quadrilateral with at least one pair of parallel sides. The diagonals of a trapezoid connect the non-parallel vertices, and their lengths can vary depending on the specific dimensions of the trapezoid. In a trapezoid where the non-parallel sides are of equal length, the diagonals will be congruent, but this is not always the case.
Are both diagonals of any parallelogram longer than the sides?
Yes.
