dude its called a TRAPAZOID didnt u learn that in math? Crystal
The rectangle is 12 units by 3 units.
a triangular prism is different from a rectangular prism because: their names are different a triangular prism has a triangle for its' base a rectangular prism has a rectangle base a triangular prism has less sides than a rectangular prism a rectangular prism has more sides than a triangular prism
Since the perimeter is 18, the sum of the length and breadth is 18/2 units = 9 units. Draw a straight line on the grid of less than 9 units. At right angles to that line, draw another line so that the two lines have a combined length of 9 units. These two lines are the two adjacent lines of the rectangle. Use the grid to draw line parallel to these so that you have a rectangle.
Let x be L, so W = x - 2 P = 2(L + W) substitute 28 for P, x for L, and x - 2 for W; 28 = 2(x + x - 2) divide by 2 to both sides; 14 = 2x - 2 divide by 2 to both sides; 7 = x - 1 add 1 to both sides; 8 = x x - 2 = 8 - 2 = 6 So L = 8 cm and W = 6 cm. A = LW = 8 x 6 = 48 Thus the area is 48 cm^2
Incorrect, a triangle will never have more or less than three sides.
A trapezoid has only 1 pair of parallel sides of different lengths
A quadrilateral always has 4 sides... no more no less.
Trapezoid
A quadrilateral has 4 sides anda hexagon has 6 sides. So the polygon between them is the one that has 5 sides. That is the pentagon.
More or less the same as a square. 4 right angles (90 degrees) 2 pairs of parallel lines.If you can guarantee that the opposite sides of your 4-sided figure are parallel,OR that they're equal, AND that the figure has one right angle inside it, thenyou can be sure that it's a rectangle.
A quadrilateral, pentagon or hexagon.
No. For any random quadrilateral, they are actually "never" congruent. The probability of the sides being so is infinitely less than the probability they will not be.
Not exactly. A trapezoid has exactly one pair of parallel sides -- no more and no less.
A trapezoid has only 1 pair of parallel sides of different lengths
Yes.Yes.Yes.Yes.
A right angle triangle
A quadrilateral is a 4 sided closed shape, like a square or rectangle. There's also a rhombus (tilty, squished square), diamond, parrallelogram, and many others. As long as it has 4 sides and is closed, it's a quadrilateral. Quad means 4. Every quadrilateral has 4 angles inside, as well as 4 sides. An easy example is a square, or rectangle. Pick up a textbook if you're having trouble visualizing, or draw a square on a piece of paper. Squares (and rectangles) have four 90 degree angles. 4*90 = 360 degrees in a quadrilateral. Side note: The sum of the angles in a triangle is 180 degrees. What about shapes with 5 sides... 6 sides... or more? Do you think a 5-sided shape will have 360 degrees in angle sums? More or less?
