by definition all 4 sided 2D shapes with equal lengths are parallelograms because the lines on opposite sides must be parallel. However you may be looking for the word rhombus or diamond. Although I don't think you could forget the word diamond.
A parallelogram has four sides and four angles. The opposite sides of a parallelogram are parallel and equal in length, and the opposite angles are also equal in measure. The sum of the interior angles of a parallelogram is always 360 degrees.
You must be looking at a Venn diagram of different kinds of quadrilaterals. Although I can't see your diagram, the most likely thing to look for is a trapezoid, or maybe a kite. Of course, there are many quadrilaterals with nothing special about them, they're just quadrilaterals.
The Amazonian vampire Zafrina can create illusions in Twilight. I hope that's the answer you were looking for.. :D
It depends on the type of parallelogram:The classic generic-looking parallelogram, having no right angles, and having adjacent sides of unequal length, has no lines of symmetry (only point symmetry about the point of intersection of the diagonals).Special types of parallelograms are as follows:A square has 4 lines of symmetry: horizontal, vertical, and one containing each diagonal.A non-square rhombus has two lines of symmetry: one containing each diagonal.A non-square rectangle has two lines of symmetry: horizontal and vertical.
Well, honey, a parallelogram has a grand total of zero acute angles. It's all about those congruent opposite angles being the same size, which means they're either both obtuse or both acute. So, if you're looking for acute angles, you better go find yourself a different shape to play with.
They sort of see it. You are just looking it in a different way.
Try looking at a rhombus, maybe that will help.
To find the area of a parallelogram, multiply the base length by the height of the parallelogram. The formula for the area of a parallelogram is A = base * height.
The picture you are looking for is a parallelogram.
A slanted rectangle is a parallelogram in the same way that a slanted square is a rhombus.
Optical Illusions is all about math and you will know by the time you finish reading this very short, but general status about optical illusions. Optical has a lot to do with math because when your brain is looking at something, you know exactly what it is. But when a professional tells you what the object actually is, you suddenly see it, your brain is doing all the math but it realizes it's messing up and looks at it more carefully.
