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 .
So we construct parallelogram As :
Step 1 ) Draw a line AB = 6 cm
Step 2 ) Construct angle 60 at point A , with the help of protector draw angle ray AX
Step 3 ) We know Adjacent angle in parallelogram are supplementary , so A + B = 180
60 + B = 180
B = 120
So we form 120 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 :
