The area of a regular heptagon can be found by breaking the heptagon into seven congruent triangles and then taking the sum of their areas?
yes True
How many triangle fit in a hexagon?
That would depend on which hexagon and what triangles. A small hexagon might not have room for any large triangles. A large hexagon will have room fro many small triangles.If you have a regular hexagon and connect the vertices you will have drawn six equilateral triangles
Given a regular heptagon how many obtuse angled triangles are there?
there are 14 obtuse angled triangles. to work this out, join all the vertices together, making a 7-pointed star. then count all the obtuse-angled triangles. i got 14...you might get a different answer, if so, i apologise. lol i know where u got this question from... anyway hoped i helped :)
How do you make a heptagon out of six equilateral triangles?
Arrange the triangles to make a regular hexagon. Then move one of the triangles so that its side lies alongside the side of one of its former neighbours.
Can regular heptagons and equalateral triangle tile a flat surface?
Equilateral triangles can tile a plane, but regular heptagons cannot; nor can they tile the plan together. Where vertices meet (at a point on the plane) there is a complete turn of 360°. Each vertex of an equilateral triangle is 60°; 360° ÷ 60° = 6, a whole number of times, so a whole number of equilateral triangles can meet at a vertex of the tiling. Each vertex of a regular heptagon is 128 4/7°; 360° ÷ 128 4/7° = 2 4/5 which is not a whole number, so a whole number of regular heptagons cannot meet at a vertex of the tiling, so there will be gaps. With one regular heptagon there are 360° - 128 4/7° = 232 3/7°, but this cannot be divided by 60° a whole number of times, so one regular heptagon and some equilateral triangles cannot meet at a vertex of the tiling without gaps. With two regular heptagons there are 360° - 2 x 128 4/7° = 102 6/7°, but this cannot be divided by 60° a whole number of times, so two regular heptagons and some equilateral triangles cannot meet at a vertex of the tiling without gaps. With three or more regular heptagons, they will overlap when trying to place them on a plane around a point - leaving no space for any equilateral triangles.
How many traingles do a heptogan have?
You can fit 7 regular/equilateral triangles inside a Heptagon since a Heptagon has got 7 sides and vertices.
Which of these two regular polygons has the largest exterior angle heptagon triangle?
It is the regular triangle whose exterior angles are greater than the regular heptagon
Which of these two regular polygons has the larger interior angle triangle or heptagon?
heptagon
Which of these two regular polygons has the largest interior angle triangle or heptagon?
It is the regular 7 sided heptagon whose interior angles are greater than the regular 3 sided triangle
Does regular heptagon tessellate?
True * * * * * No. The only regular polygons that will tessellate are a triangle, a square and a heagon. So a regular heptagon will not tessellate.
How many equilateral triangles in an heptagon?
None but there are 6 in a regular hexagon
Will a regular heptagon and equilateral triangle tile a plane?
No.
Can a regular heptagon and equilateral triangle tile a plane?
No
Which has a larger exterior andle a triangle or heptagon?
That depends on the type of triangle it is but if it's an equilateral triangle then its exterior angle is greater than that of a regular heptagon
The area of a regular heptagon can be found by breaking the heptagon into seven congruent triangles and then taking the sum of their areas?
yes True
Which of these two regular polygons has the longer interior angle triangle heptagon?
If, by longer, you mean larger, the answer is a heptagon.
What regular polygon can you make with six triangles?
draw a hexogon and make six triangles no more than six unless you are doing a different math problem than i am.
