proper steps of construction of quadrilateral

spammers not to come her. e. ​

Answer 1

Construct quadrilaterals when two adjacent sides and three angles are known.
Draw PQ = 3.5 cm and construct PQX = 135.
Cut off QR = 6 cm.
Make QRY = 120°
Make QPZ = 75° at M.
Mark that point, where RY and PZ meet, as S.
We get the required quadrilateral PQRS.

Answer 2

Answer:-

When four sides and one diagonal are given

When two diagonals and three sides are given.

When two adjacent sides and three angles are given.

When three sides and two included angles are given.

When other special properties are known.

Let us take up these constructions one-by-one.
