What else can I help you with?
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
