1. ➤ Correct Question :-

   Construct a triangle ABC in which BC = 5.5 cm, ∠B = 75° and ∠C = 45°

   ➠ Steps :-

   • First, draw a line segment BC of 5.5 cm.
   • Next, take a protractor and keep it’s mid-point on the point B and draw a ray measuring 75°.
   • Again, take a protractor and keep it’s mid-point on the point C and draw a ray measuring 45°.
   • Now, join both rays on one point. If they don’t meet, extend them until they meet. Name it as point A.
   • Finally, the triangle is constructed.

   ➸ Instruments used :-

   • Ruler:– The ruler is used to draw the line segments of accurate measurements and the drawn lines should be correct and straight always.
   • Protractor:- The protractor is used to draw the rays of accurate measurements of degrees. It’s also used to measure the angles given.

2. Construction of triangle:-

   • Draw one side (bc) of the triangle using a ruler of 5.5 cm.

   • Draw another side (lb) of the triangle using a ruler of 7.5 cm.

   • Draw last side (lc) of the triangle of 4.5 cm.
