    2. Best Answer
      Construct a right triangle whose base is 12 cm and sum of its hypotenuse and other side is 18 cm.

      Steps of construction
      (i) Draw a line segment AB = 12 cm.
      (ii) At point A, Using ruler and compass, draw an angle ∠BAX = 90°.
      (iii) Taking A as centre and 18 cm as radius, draw an arc which intersect AX at D.
      (iv) Join B to D. Draw a perpendicular bisector (MN) of BD which intersects AD at C.
      (v) join B to C. Triangle ABC is the required triangle.
      Justification
      Point C lies on the perpendicular bisector of BD.
      So, BC = CD
      Here, AD = AC + CD
      ⇒ AD = AC + BC [∵ BC = CD]
