ABC is a triangle in which BC = 10 cm, ...

ABC is a triangle in which BC = 10 cm, CA = 6 cm and AB = 8 cm. Which one of the following is correct ?

A

ABC is an acute angled triangle

B

ABC is an obtuse angled triangle

C

ABC is a right angled triangle

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
C
Given a `Delta`ABC in which BC = 10 cm,
CA = 6cm and AB = 8 cm.
Since, `CA^(2)+AB^(2)=36 + 64 = 100 = BC^(2)`
`therefore Delta`ABC is a right angled triangle.
