Question

A B C D , Construct a Parallelogram AB= 4 cm A = 60 BC = 5 cm write step of constouction.?​

Answer 1

Step-by-step explanation:

AB=DC=4cm [Opposite sides are equal]

BC=AD=5cm

∠B=60

∘

and,

∠A+∠B=180

∘

[Sum of cointerior angles]

⇒∠A=120

∘

Steps of construction :

Step 1. Draw a line segment AB=4cm

Step 2. Draw a ray BX such that ∠ABX=60

∘

Step 3.Mark a point C such that BC=5cm

Step 4. Draw a ray AY such that ∠YAB=120

∘

Step 5. Mark a point D such that AD=5cm

Step 6. Join C and D.

Hence, ABCD is a required parallelogram.

solution.

Answer 2

Answer:

In parallelogram ABCD

AB=DC=4cm    [Opposite sides are equal]

BC=AD=5cm  

∠B=60 °

and,

∠A+∠B=180 °  

[Sum of co-interior angles]  

⇒∠A=120 °

Step-by-step explanation:

Step 1. Draw a line segment AB=4cm  

Step 2. Draw a ray BX such that ∠ABX=60 °

Step 3. Mark a point C such that BC=5cm  

Step 4. Draw a ray AY such that ∠YAB=120 °

Step 5. Mark a point D such that AD=5cm  

Step 6. Join C and D.
