Question

In an isocelese triangle angel opposite to the unequal side is 80° find the other angel​

Answer 1

Step-by-step explanation:

The angle of the same side of an triangle is 50°

Answer 2

Answer:

The other two angles will be of 50° each

Step-by-step explanation:

Let the Δ ABC be the isosceles trangle

Therefore,

Given,Isosceles triangle:- AB=AC & ∠ C=80°

Therefore ∠A=∠ B----------1.  

By angle sum property of triangle,

∠ A + ∠ B + ∠ C=180°

Therefore,

∠ A + ∠ B + 80° = 180°

∠ A + ∠ B = 100

We know that ∠ A = ∠ B

Therefore,

∠ A + ∠ A = 100°

2 ∠ A = 100°

∠ A = 50°

Therefore,

∠ B = 50°
