The sides of `Delta ABC` measure 5 cm, 12 cm and 13 cm. What type of a triagnel is ABC ?

Text Solution

Verified by Experts

Since no two sides are equal , ABC is a scalence triangle.
Further, `5^(2)+12^(2)=13^(2)`.
Since, the square on the longest side is equal to the sum of the squares on the other two sdes, ABC is a right angles triangle.
