How Construct a parallelogram ABCD in which a b is equal to 7 and ac is equal to 10 cm and BD is equal to 8 centimetre break at remember that diagonals of the parallelogram bisect each other
Answers
Step-by-step explanation:
We need
a compass
a scale
and
a pencil.
Draw a line 7cm long.
Name it AB.
AC = 10 and BD= 8 (given).
Half of these are 5 and 4.
So with A as centre draw an
arc of 5 cm
from B draw an arc of 4 cm
Both arcs should be long enough in the right direction so that they intersect.
We name this intersection O.
From A draw a line AC through O ; extend it to 10 cm.
From B draw BD through O ;
extend it to 8 cm.
Join B-C-D-A.
Our parl'gram is ready.
Answer:
step 1-->
----------
drawing AC=10cm as base and drawing perpendicular bisector of AC.
step 2--->
----------
now we know that diagonal of ||gm bisect each other so taking radius equal to 8/2=4cm and taking o as centre drawing two arcs one above o and one below o
step 3--->
----------
now taking 7cm as radius and taking A as centre and taking C as centre drawing two arcs which interest previous arcs at B and D
step 4--->join A and B, B and C, A and D, C ----------
and D to get a ||gm ABCD
