To construct a right triangle ABC right angled at C when its hypotenuse is AC and one side is BC is given, we follow the following steps :

Construct a right triangle PQR in which ∠Q = 90

Step 1: Draw QR = 4 cm.

Step 2 : Using compass, at Q draw ∠RQK = 90

Step 3 : Cut off RP = 6 cm.

Step 4 : Join P and R.

Now we get the required ΔPQR.

1) If the sides of triangle are 3cm,4cm and 5cm then what type of triangle you will get after constructing it?

2) Construct a right angled triangle ABC where AB = 4.5 cm, AC = 5.8 cm and angle A = 90

3) In a triangle PQR, if ∠P=90
