In a right angle triangle ABC right angled at B, if AB = 5 cm, AC = 13 cm, then BC is
According to Pythagoras theorem
AC2= AB2+BC2 ⟹ BC2=AC2−AB2
BC2= 132 - 52
= 169 - 25 = 144
⟹ BC = 12 cm
In a right angled triangle ABC, ∠B=90°.
If AC=13 cm, BC=5 cm, find AB
In a right triangle ABC, ∠B = 90°.
(a) If AB = 6 cm, BC = 8 cm, find AC
(b) If AC = 13 cm, BC = 5 cm, find AB
