1. Construct a triangle RST right angled at T in which ST = 6.2 cm and SR = 8.3 cm.

Answer :

We follow these steps , to construct triangle RST :

Step 1 : Draw a line ST  =  6 . 2  cm

Step 2 : Take any radius and draw a semicircle by taking center  " T " , That intersect our line ST at " A " .

Step 3 :  With same radius take center " A "  draw and arc that intersect semicircle at  " B "  and draw another arc by taking center  " B " that intersect semicircle at " C " .

Step 4 : With same radius draw two arc by taking center B and C that intersect at " D " .

Step 5 : Draw a line  TD and extend it .

Step 6 :  Now take radius of 8.3 cm and center "  S " draw an arc that intersect our extend line ( TD )  at R .

Step 7 :  Join SR , We form our triangle RST .
