Question

Construct a triangle ABC in which BC = 3.4 cm AB -AC = 1.5 cm and ∠B = 45° Justify your construction

Answer 1

Answer:

Step 1: Draw a line segment BC = 3.4 cm.

Step 2: Draw ∠XBC = 45°.

Step 3: Draw an arc which intersects XB at point D form point B and with radius 1.5 cm. So, BD = 1.5 cm.

Step 4: Join line segment DC.

Step 5: Draw a perpendicular bisector of DC which intersects BX at A.

Step 6: Join line segment AC. Hence, △ABC is the required triangle.
