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.

Are opposite angles in a parallelogram supplementary?
No, they are equal. Adjacent angles are supplementary in a prallelogram.
How can you construct a parallelogram of 6.5cm and 4.3cm without usind a protractor?
Well it's a simple question. It's necessary to note that a prallelogram is a group name for so many shapes among which you have the square, rectangle and rhombus. You can get more about the properties of a parallelogram from your text. It will will be quite easy to construct a square, rectangle or rhombus using the information given and if the angles of the parallelogram is not a right angle, then I've got to assume some figures. Let's say one of the angles between the two sides of the parralelogram is 600 then the adjacent angle will be 1800 - 600 = 1200 (Anyway no calculation is required at this stage) steps: 1. Draw line AB = 6.5cm 2. With centre A, draw a semi circle and on it construct an angle of 600 ( You sure know how to construct angle 600 ) 3.On the 600 mark extend a line 4.With centre A, mark off 4.3cm on the extended line at B. 5. With B as centre and radius 4.3cm draw an arc above B at C 6.With D as centre and radius 6.5cm cut the arc at C 7. Join B to C, and C to D to give parralelogram ABCD with the angles 600,600 ,1200 , 1200and sides: AB= 6.5cm, BC = 4.3cm, CD = 6.5cm and DA = 4.3cm
How many right angles does a prallelogram has?
It can have four, it doesn't have to have any.
What mathematic did Fibonacci do?
Fibonacci study trigonometry it is dealing with trangles
What two shapes can be made from a quadrilateral?
two right trangles
What was the star of david made out of?
two trangles put together
Are opposite angles in a parallelogram supplementary?
No, they are equal. Adjacent angles are supplementary in a prallelogram.
Can you give a picture of what a prallelogram looks like?
here you go /////// look at the outline of the shape i made
How is a trapezoid different from a prallelogram?
A trapezoid has only 1 pair of parallel sides while a parallelogram has 2 pairs of parallel sides.
Does a prallelogram have to have diagonals the same length?
In general, the diagonals of a parallelogram are NOT the same length. They're equalonly when the parallelogram is either a rectangle or a rhombus (including square).
How much degrees is there in a rectangle?
360 degrees, 90 degrees per angle, you can make two trangles inside of it, and triangles are 180 degrees
Is ABC trangle an trangle DEF If so name which similarity postulate or theorem applies.?
None; because there is no justification for assuming that the two triangles (or trangles, as you prefer to call them) are similar.
Why Is a rectangle a prallelogram?
A parallelogram is a shape with 4 sides whose opposite sides are parallel. A rectangle meets this definition. It is a special type of parallelogram where the angles between sides all equal 90 degress.
How many sides does a pentogonal rotunda have?
The Pentagonal Rotunda has 20 vertices, 17 faces and 35 edges. The Pentagonal Rotunda contains 10 trangles, 6 pentagons and 1 decagon.
