Question

Name the types of following triangles :
$△ L M N$ with $m ∠ L = 30^{\circ}, m ∠ M = 70^{\circ}$ and $m ∠ N = 80^{\circ}$ .

Open in App

Solution

It is given that in $Δ L M N$ , we have
$∠ L = 30^{\circ}$ , $∠ M = 70^{\circ}$ and $∠ N = 80^{\circ}$
Since, all the angles of the given triangle measure less than $90^{\circ}$ , therefore, the given triangle is an acute triangle.

Name the types of following triangles :△LMN with m∠L=30∘,m∠M=70∘ and m∠N=80∘.

It is given that in ΔLMN, we have∠L=30∘, ∠M=70∘ and ∠N=80∘Since, all the angles of the given triangle measure less than 90∘, therefore, the given triangle is an acute triangle.
