Which is the odd one out, a square, a circle, a rectangle or a triangle?

could be circle because it doesn't have any sides or angles\n\ncould be rectangle because it is not proportional (side-wise.. and only if the triangle is equilateral)\n\ncould be triangle because if all shapes are placed right-side and divided into four equal parts, like a cross-hair, the triangle is the only one without equal portions.

If it's a square, (60 x 60) then probably 8.\nIf it's a circle (r=60) then probably 10.\nIf it's a cirlce (d=60) then probably 6

Draw a picture - a square with corners (0,0), (2,0), (0,2), (2,2), showing the range of possible values for x and y.\nNow, what part of that square has the difference < 1? Its a hexagon to be precise; its the entire square except for a little triangle at the top left, and a little triangle at the bottom right. The two sloping sides go from (0,1) to (1,2) and (1,0) to (2,1).\nThose triangles each have area 1*1/2 = 0.5, so area 1 combined.\nSo the total area left is 4-1 = 3, so the answer is 3/4.

Ahh, a triangle. Since you know the two long sides of the triangle and the angle between them, use the Lore of Co-signs to get the third side (Law of Cosines).

i think its a triangle

Imagine a square that is 6 inches across on each side.\n\nThat's the simplest example.\n\nAny rectangle where the length and width have a product of 36 works also.  It can be 9 inches on one side and 4 on another.  It could even be 1 inch wide and 36 inches long (much like a yardstick).\n\nBut it's not just rectangles.  The area of a circle is pi (approx. 3.14) times the square of the radius.  So, a circle with 3.4 inches for a radius is about 36 square inches.

You might be thinking of a Reuleaux (or Rouleaux) triangle, but it has rounded sides, not rounded corners.

Square- four equal, parallel sides, all right angles\nRectangle-four parallel sides, not necessarily all equal, with four right angles\nTrapezoid- one pair of parallel sides\nRhombus- all sides parallel, but not at right angles

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!

6√2\n\nRemember it's a square so the sides are all the same length, and the area is s^2\n\nso s^2=36==>s^2-36=(s-6)(s+6)=0 so s is either 6 or -6.  -6 makes no sense here, so it is obviously 6.\n\nNow, since we have a square we can "draw" (imagine) a line at the diagonal, and that makes a right triangle (since the corners of a square are all 90º) with legs 6 and 6.  using the Pythagorean relation, we have d^2=s^2+s^2=6^2+6^2=72.  Thus d^2-72=(d-6√2)(d+6√2)=0.  Thus d is either 6√2 or -6√2, and again is obviously the positive one :)

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.
