Question

AB = 6.3 cm, BC = CD = 4.2 cm and
ZABC = ZBCD = 90°.​

Answer 1

Construct a quadrilateral ABCD, when AB=6.3 cm,BC=CD=4.2 cm and ∠ABC=∠BCD=90

∘

.

Find the length of side AD and m∠BAD.

ANSWER

Step 1: Draw base BC of length 4.2 cm.

Step 2: Draw lines of at an angle of 90

∘

from points B and C.

Step 3: Make an arc of radius 6.3 cm on the perpendicular line from B and mark the point as A.

Step 4: Make an arc of radius 4.2 cm on the perpendicular line from C and mark the point as D.

Step 5: Join A−D

□ABCD is the required quadrilateral.

Upon measuring AD, we get the length as 4.7 cm approx. and m∠BAD=65
