Construct `trianglePQR` if PQ=5cm, `mlfloorPQR=105^o` and `mlfloorQRP=40^o` (Hint: Recall angle sum property of a traingle).

Construct triangleABC with BC=7.5cm, AC=5cm and mlfloorC=60^o .

Construct the right angle trianglePQR where mlfloorQ=90^o QR=8cm and PR=10cm.

Construct ABC, give mlfloorA=60^o , and mlfloorB=30^o and AB=5.8cm.

Construct an isosceles right-angled traingle lfloorABC, where mlfloorACB=90^o . And AC=6cm.

Solve the following: In a isosceles traingle, the base angles are equal. The vertex angle is 40^o . What are the base angles of the traingle? (Remember, the sum of three angles of a traingel is 180^o ).

Construct an isosceles traingles in which the length of each of its equal sides is 6.5cm and the angle between them is 110^o .

Construct a quadrilateral ABCD in which the three sides are AB=5cm,BC=6 cm and CD=7.5 cm.The two included angles are /_B = 105^@ and /_C = 80^@

In the adjacent figure lines PQ and RS intersect each other at point O. If anglePOR : angleROQ = 5: 7, find all the angles.
