Question

If the vertical angle of an isosceles triangle measures 60 degree then the triangle is
a) an isosceles triangle
b) an equilateral triangle
c) a right angled triangle
d) a scalene triangle ​

Answer 1

Answer:

isosceles triangle

Step-by-step explanation:

60, 60

…./…../….

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:

x = 180-120

x = 60

= 60°

option b is correct
