What is the difference between a quadrilateral an triangle?
A triangle is not a quadrilateral, but a parallelogram and trapezoid are.
Is a triangle a parallelogram or quadrilateral?
It is neither because a triangle only has 3 sides whereas a parallelogram is a 4 sided quadrilateral
Is a triangle a parallelogram or a quadrilateral?
It is neither because a triangle is a 3 sided polygon whereas a parallelogram is a 4 sided quadrilateral
A quadrilateral that is not a parallelogram or a trapezoid?
a triangle
What quadrilateral is not a parallelogram or a trapezoid?
triangle
Is a trangles a prallelogram?
no. a triangle is not a parallelogram. First of all, a parallelogram should be a quadrilateral, and quadrilateral forms are figures which has four sides. secondly' a parallelogram should have two pairs of parallel sides. a triangle doesn't even have a pair of parallel sides.
Why the area of a triangle is half that of a parallelogram?
If you put two of ANY triangle hypotenuse to hypotenuse the shape will have 4 sides (thus a parallelogram or quadrilateral).
What is the proper name of the quadrilateral below a parallelogram b triangle c square d rectangle?
parallelogram
Is a scalene triangle a parallelagram?
NO; by definition a parallelogram is a quadrilateral with two sets of parallel sides, while a triangle has 3 sides.
Can an equilateral triangle be a parallelogram?
No. Every triangle has 3 sides, and every figure with 3 sides is a triangle. So no triangle can be a parallelogram. Every parallelogram has 4 sides, and every figure with 4 sides is a quadrilateral. So no parallelogram can be a triangle.
Can an equilateral and equilangular triangle ever be a parallelgram?
No because a parallelogram is a quadrilateral that has 4 sides but any triangle has only 3 sides.
How can you used a triangle to prove quadrilateral is a parallelogram?
A quadrilateral, in general, is not a parallelogram. If it is a parallelogram then you will have some additional information about its sides and angles. If you do not have such information it is not possible to prove that it is a parallelogram. Draw a diagonal which will divide the quadrilateral into two triangles and use the additional information that you have to show that the triangles are congruent. This can then be used to show equality of sides or of angles: the latter can then be used to show that sides are parallel. Note that the choice of which diagonal may influence how (if at all) you proceed.
