**Construct quadrilaterals to the given measurements, the order of the letters is each case is A.B.C.D**

**AB = 4.8cm. BC = 4.4cm. CD = 7cm. DA = 3.4cm. BD = 6.2cm.**

Steps of construction

- Draw AB = 4.8cm.
- With A as centre and 3.4cm radius draw an arc.
- With B as centre and 6.2cm as radius drawn an arc to intersect the first at D.
- Join AD and BD.

- With B as centre and 4.4cm as radius drawn an arc.
- With D as centre and 7cm as radius draw an arc to intersect the above at C.
- Join DC and BC.

ABCD is the required quadrilateral

**AB = 6.3cm. CD = 6.5cm. BC = 3.8cm. AC = 4.5cm. AD = 3.6cm.**

**Solution:**

Steps of construction:

- Draw AB = 6.3cm
- With A as centre and 4.5cm radius draw an arc.
- With B as centre and 3.8cm as radius drawn another arc to intersect the above at C.
- Join AC and BC.
- With C as centre and 6.5cm as radius drawn an arc.
- With A as centre and 3.6cm as radius draw another arc to intersect the above at D.
- Join AD and CD.

ABCD is the required quadrilateral.

**AB = CD = 5.2cm. BC = AD = 3.2cm. BD = 7.2cm.**

**Solution:**

Steps of construction:

- Draw AB = 5.2cm
- With A as centre and 3.2cm radius draw an arc.
- With B as centre and 7.2cm as radius drawn another arc to intersect the above at D.
- Join AD and BD.
- With B as centre and 3.2cm as radius drawn an arc.
- With D as centre and 5.2cm as radius draw another arc to intersect the above at C.
- Join BC and DC.

ABCD is the required quadrilateral

**AC = 5.8cm. BD = 5cm. AB = 3.8cm. BC = 5.5cm. CD = 4.5cm**

**Solution:**

Steps of construction:

- Draw AB = 3.8cm
- With A as centre and 5.8cm radius draw an arc.
- With B as centre and 5.5cm as radius drawn another arc to intersect the above at C.
- Join AC and BC.
- With B as centre and 5cm as radius drawn an arc.
- With C as centre and 4.5cm as radius draw another arc to intersect the above at D.
- Join CD, BD and AD.

ABCD is the required quadrilateral.

**AC = 5.8cm. BD = 5.6cm. AB = 3.5cm. AD = 4.9cm. CD = 4cm.**

**Solution:**

Steps of construction:

- Draw AB = 3.5cm
- With A as centre and 4.9cm radius draw an arc.
- With B as centre and 5.6cm as radius drawn another arc to intersect the above at D.
- Join AD and BD.
- With A as centre 5.8cm as radius draw an arc.
- With D as centre and 4cm as radius draw another arc to intersect the above at C.
- Join DC, AC and BC.

ABCD is the required quadrilateral.

**AC= 6cm. BD = 5.8cm. AB = 3.4cm. AD = 5.2cm. BC = 4.2cm.**

**Solution:**

Steps of construction:

- Draw AB = 3.4cm
- With A as centre and 6cm radius draw an arc.
- With B as centre and 4.2cm as radius drawn another arc to intersect the above at C.
- Join AC and BC.
- With A as centre 5.2cm as radius draw an arc.
- With B as centre and 5.8cm as radius draw another arc to intersect the above at D.
- Join AD, BD and CD.

ABCD is the required quadrilateral
