Question

. Check the given measurements whether it could make a triangle

(a) 7 cm, 2 cm and 5 cm


(b) 10 cm, 12 cm and 14 cm.​

Answer 1

They do not make triangles.

Explanation:

You automatically know that c is going to be the biggest number of each triangle since it is the largest side. So you would use both of these formulas:

a² + b² = c²

`2^(2)` +
`5^(2)` =
`7^(2)` which is false

10² + 12² = 14² is false as well

Hope this helps!!
