Can you construct the quadrilateral PQRS, PQ =4 cm, QR = 4.8 cm, angleP = 75^@ , /_Q= 100^@ and angleR= 120^@ , if we have an angle of 100^@ at P instead of 75^@ ?Give reason.

Do you construct the given quadrilateral ABCD (with AB=5 cm, BC= 4.5 cm, CD = 6 cm, /_B = 100^@, /_C = 75^@ ) by taking BC as base instead of AB ? If so, draw a rough sketch and explain the various steps involved in the construction.

A student attempted to draw a quadrilateral PLAY given that PL =3 cm, LA=4 cm ,AY =4.5 cm, PY=2 cm and LY =6 cm. But he was not able to draw it why ? Try to draw the quadrilateral yourself and give reason.

Can you construct a triangle ABC with BC = 6 cm, angleB=60^(@) and AB + AC = 5cm.? If not, give reasons.

Can you construct the given AC = 4.5 cm and BD = 6 cm quadrilateral (rhombus) taking BD as a base instead of AC ? If not give reason.

Sushant prepared a problem. Construct /_\ XYZ in which XY =2 cm , YZ = 8 cm and XZ = 4 cm. He also drew the rough sketch as shown is figure (i).Reading the problem, Srija told Sushant that it would not be possible to draw the triangle with the given measurements. However, Sushant started to draw the diagram as shown in figure (ii). Check whether Sushant can draw the triangle. If not why? Discuss with your friends. What property of triangles supports Srija's idea?

Construct triangleABC , right angle at angleA and BC 6 cm, AB-5 cm.Step (1) Draw a line segment of P AB=5 cm.Step (2) Join, B, C to the required triangleABC . Step (3) Draw a rough sketch of triangleABC with given measurements. Step (4) Construct a ray bar(AX) perpendicular to AB at A.Step (5) Draw an are from B with radius 6cm to intersect bar(AX) at C.

Let us do the following activity to understand the mendelian principles of heredity. Materaials required: a. 3cm length and 1 cm breadth chart pieces -4 b. 2 cm length and 1 cm breadth chart pieces -4 c. Red byuttons -4 d. white buttons -4 e. chart, scale, sketch pen penil, 2 bags. Method: Prepare a chart with 2x2 boxes along with numbe and symbol as shown in the figure. Game 1: Monohybrid cross (starting with hybrid parents) To start with take 1,2 or 3,4 . In case you start 1,2 pik all the 16 log and short pieces and prepare such paris in each of which you have a long and short piece. Take 4 pairs each of long and short strips and put them in two separate bags. Now each bag contains 8 strips (4 long and 4short). One bag say 'A' represents mael and the bag 'B' represents female . Now rendomly pick one strip each from bag A and B and put them together in the 1 on the chart. Keep picking out the strips and arrange them in the same manner till your bags are empty. Same time your boxes in the chart are filled with paris of strips. you might have got the following combinations, two long strips, one long and one short strip, two short strips. (Q) E. What can you coclude from this game?
