how to make parallogam with protector?also show its angle and also show its measure of its opposite side ? to measure the opposite side angle we have put the protecctor in downward direction?means

TO draw a parallelogram using protector , we have some information about

Adjacent sides of parallelogram is 6 cm and 4 cm and one of the base angle is 60$\xb0$ .

So we construct parallelogram As :

Step 1 ) Draw a line AB = 6 cm

Step 2 ) Construct angle 60$\xb0$ at point A , with the help of protector draw angle ray AX

Step 3 ) We know Adjacent angle in parallelogram are supplementary , so $\angle $ A + $\angle $ B = 180$\xb0$

60$\xb0$ + $\angle $ B = 180$\xb0$

$\angle $ B = 120$\xb0$

So we form 120$\xb0$ at B ,with the help of protector and draw angle ray as BY ,

Step 4 ) we know opposite sides are equal in length , So we take radius of 4 cm and center A form an arc that meet our angle line AX at D . And we take radius of 4 cm and center B form an arc that meet our angle line BY at C .

Step 5 ) Join CD , we form a parallelogram , As :
