what is a equilateral traingle?and how many sides does it have?

By definition an EQUILlateral is a triangle made up of 3 lines of the same legnth. Having 3 sides makes it a TRI angle. If it had 4 sides, it would be a square, 5 sides would be a pentagon.

since both sets of sides are parallel, it has to be at least a parallelogram (rules out trapezoid). And since two adjacent angles aren't the same, that rules out rectangle and square (both of which have all right angles). It can be either a rhombus or a more general parallelogram.

Draw a triangle, an equilateral triangle, that is : each angle is 60 degrees. Each particle is placed at the vertex.

Isosceles triangles have only two equal sides. The scalene has no equal sides, the right has a right angle in it, and the equilateral has all equal sides. Hope this helps!\n\n.:Lark:.

number of sides, congurency?, size of angles, distinguishing characteristics

By definition, both are the same.  An equilangular triangle is a triangle with all three angles equivalent, while an equilateral triangle is a triangle with all three sides the same length.  By geometric theorem, if all angles of a triangle are the same, then all sides are the same, and vice versa.\n\nThe term equilateral is far more used than equiangular, even though they are equivalent.\n\nhttp://72.14.203.104/search?q=cache:qgLljdKxu8oJ:mathforum.org/geopow/solutions/solution.ehtml%3Fpuzzle%3D208+equilangular+triangle+equilateral&hl=en&gl=us&ct=clnk&cd=6

The shape with 120 sides is called Hexakis Icosahedron.\n\nThe Hexakis Icosahedron has 62 vertices, 120 faces and 180 edges. (The Hexakis Icosahedron is the only polyhedron with 120 faces.) \n\nThe Hexakis Icosahedron contains 120 triangles. \n\nThe dual of the Hexakis Icosahedron is the great rhombicosidodecahedron. \n\nI hope I answered your question. All the best.

i don;t know all of them, but here are a few:\n-rectangle\n-square\n-rhombus\n-parallelogram\n-kite\n-trapezoid\n-and closed abject with four sides!\n-cyclic quaDrilateral     \n-cyclic-inscriptable \n\ncheck out the site dr. math for more info on quadrilaterals!

no, a circle has infinite lines of symetry. For an equilateral triangle, i believe there r only 3

false. a quadrilateral is a four sided polygon. so a square and rectangle are also quadrilaterals. a trapezoid is a four sided polygon with 2 opposite sides that are parallel to each other.

a hexangle would be 6 degrees or an offset of 6 degrees if you are speaking of a tool or a deflection.\n-------\nIf you are speaking of a hexagon:\n\nAll regular polygons have a total of 360 degrees for their center  angles, and all are equal.\n\n360/6=60 degrees.\n----------\n\nThe sum of the angles of a triangle is 180 degrees.\n\nSo each segment of the hexagon will form a triangle with the center point which is an isosceles triangle, with an apex angle of 60. The other two angles will be equal as they are opposite sides of equal length, and they will total 180-60=120. The three angles of the triangle will be 60, 60 and 60, so we know it is also an equilateral triangle.\n\nThe angle between one segment of the side of the hexagon and the next will then have to be 2x60=120 degrees because all the segments will be the same.

The area of an equilateral triangle is\nA = (1/4)sqrt(3) * a^2, where a is the length of the side.\nSince the triangle is equilateral, you know that the length of each side is 10/3.\nThe area is\nA = (1/4)sqrt(3) (10/3)^2\nA = (1/4)sqrt(3) (100/9)\nA = (25/9)sqrt(3)

infinitly as many... there are millions of figures... triangle (3 sides) square (4 sides) pentagon (5 sides)... I wonder what you call a figure with 100,000 sides... hehe

word for word from MathWorld\n\nA regular polygon is an -sided polygon in which the sides are all the same length and are symmetrically placed about a common center (i.e., the polygon is both equiangular and equilateral). Only certain regular polygons are "constructible" using the classical Greek tools of the compass and straightedge. \n\nThe terms equilateral triangle and square refer to the regular 3- and 4-polygons, respectively. The words for polygons with  sides (e.g., pentagon, hexagon, heptagon, etc.) can refer to either regular or non-regular polygons, although the terms generally refer to regular polygons in the absence of specific wording.

Well, lets see if we can generate a pattern.\n\nA 3-sided polygon (aka a triangle) has no diagonals\nA 4-sided has 2\nA 5-sided has 5 (1-3, 2-4, 3-5, 4-1, 5-2)\nA 6-sided has 9 (1-3, 1-4, 1-5, 2-4, 2-5, 2-6, 3-5, 3-6, 4-6)...\nand so on.\n\nA polygon with n sides has n(n-3)/2 diagonals. The answer for 42 is left as an exercise for the reader ;)
