Question

two line segment AB 4.5and CD 6cm.using these measurements draw the line segment CD_AD​

Answer 1

SOLUTION :

Given, BD = 8 cm, AD = 4 cm, ∠ABC  = 90° and BD⊥AC.

we know that ,If a perpendicular is drawn from the vertex containing a right angle of a right triangle to the hypotenuse then the triangle on each side of the perpendicular are similar to each other and to the whole triangle.

So, ΔDBA∼ΔDCB  (A-A similarity)

BD/CD = AD/BD

[Since, triangles are similar, hence corresponding sides will be proportional]

BD² = AD x DC

(8)² = 4 x DC

64 = 4DC

DC = 64/4  

DC = 16  

Hence, the length of  CD is 16 cm..

Answer 2

Step-by-step explanation:

Answer

⇒ Draw a line segment AB=4.5cm

⇒ Take B as center and draw an angle of 60

o

.

⇒ Cut off BC=5.5cm

⇒ Take A as with radius 4.8cm and draw an arc.

⇒ Take C as with radius 5cm and draw an arc, which cuts off previous arc at point D

⇒ Join CD and AD.
