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.
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.
Are diagonals always longer than the sides?
On squares and rectangles, yes. But on parallelograms and rhombus the one diagonal can be shorter than one of the sides.
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
Are the diagonals of a kite longer than the sides?
Do this question yourself
What polygons always have congruent sides?
squares and triangles :/
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.
Do regular polygons always have equal length sides?
yae they always do:)
The diagonals of a rhombus are sometimes perpendicular?
A rhombus has 4 equal sides and the diagonals are always perpendicular
Are both diagonals of any parallelogram longer than the sides?
Yes.
