Check if the following are triangles? If yes name them? 1) #ΔTAR, ∠T= 184 and ∠A = 86# 2) #ΔDEZ, ∠D = 60 and ∠E = 60# 3) #ΔCHI, ∠C = 30, ∠H = 60 and ∠I = 90# 4)#ΔJMR, ∠J = 5, ∠M = 120 and ∠R = 67# 5) #ΔKLM, bar(KL) = bar(LM) = bar(MK)#

Below
Explanation:
1) Not a triangle
Reason: angle sum of any triangle is
2) Triangle (equilateral)
Reason: equilateral triangles all have their interior angles equal to
3) Triangle (right-angled)
Reason: angle sum does equal to
4)Not a triangle
Reason: same as 1
5)Triangle (equilateral)
Reason: all sides of an equilateral triangle is the same
