Question

constuct quadrilateral ABCD, given AB = 4.2 cm, BC = 6 cm, CD = 7 cm, angle B = 90°, angle C = 100°​

Answer 1

The given Quadrilateral ABCD can be drawn by following the steps.

Step 1: Draw a line AB=4.2cm

Step 2: With A as the centre and radius =8cm draw an arc.

Step 3: with B as the centre and radius =6cm draw another arc cutting previous arc. Label this point as C

Step 4: Join BC

Step 5: With A as the centre and radius =5cm draw an arc.

Step 6: with C as the centre and radius =5.2cm draw another arc cutting previous arc. label this point as D

Step 7: join CD and AD.

∴ The constructed quadrilateral looks like:
