Question

If the base angle of isosceles triangle is 60 the what will be the third angle ?​

Answer 1

Step-by-step explanation:

In an isosceles triangle, two angles will be equal.

Hence,

The Sum of angles of any triangle is 180

Now let other angles be x and y

So

60+x+y=180

x+y=120

Now we know that isosceles triangles have 2 equal angel

So either x=y

Then ,

2x=120

x=60 and y=60

Or, either one of x or y will be equal to the given value of the angle

So let y be equal to the given value

So

y=60,

So

x=120–60

x=60

Answer 2

Answer:

we know that two angle of isosceles base is equal.

so, 2angle 60 + 3red angle = 180°

3rd angle = 180 - 120 = 60

This is not a isosceles triangle this is a equilateral triangle.
