STEPS:
- Construct BC = 7 cm.
- Construct angle <B = 75
- Draw BX (where X is a ray)
- Cut BX at P with the radius 13 cm from B
- Draw a perpendicular bisector of CP as MN and extend backward till BP (Point at which CP is bisected is Q)
- Point A is at BP on ray MN.
- Triangle ABC
JUSTIFICATION:
- Congruence between trg. APQ and trg. ACQ by SAS
- AP = AC
- AP + BA = 13
- AC + BA = 13
Hence Proved
