Question

construct a quadrilateral ABCD in which AB = 3.8 cm. BC = 3.4 cm , CD = 4.5 cm , AD = 5cm. and angle B = 80° ​

Answer 1

Answer:

Steps of Construction:

*Draw a rough sketch and leble it's measurements

*Draw a line segment AB of length 3.8cm using a ruler

*With using a protractor draw an angle ABX = 80°

* With B as Centre draw an arc using a compass of length 3.4cm

*From A as Centre draw an arc of radius 5cm

* From C as Centre draw an arc of radius 4.5cm using a compass

*Name the point as D where the two arcs intersect

*Required quadrilateral ABCD was completed.....

Answer 2

Explanation:

The given details are AB = 3.8 cm, BC = 3.4 cm, CD = 4.5 cm, AD = 5 cm and ∠B = 80°. Steps to construct a quadrilateral: Step 1- Draw a line AB = 3.8cm Step 2- Construct and angle of 80o at B. Step 3- Cut an arc of radius 3.4cm with B as the center to mark that point as C. Step 4- Cut an arc of radius 5cm with A as the center to mark that point as D. Step 5- Cut an arc of radius 4.5cm with C as the center to intersect at point D. Step 6- Now join BC, AD and CD.

I HOPE THIS IS HELPFUL.
