Question

Raoul cuts one corner of a equilateral triangle. What can u say about the values of a and b.

Answer 1

Answer:

we can that there value will be 180-the value of their opposite angle ..as on a line the sum of angles are 180 degree

Answer 2

Answer:

After cutting one corner of the equilateral triangle, about the values of a and b ?

As we know that, all angles of a equilateral triangle are of 60°.

So,

a = 180 - x (Linear pair)

b = 180 - y (Linear pair)

Also, x + y + z = 180 (Angle sum property of triangle)

since, z = 60

so,

x + y = 180 - 60

x + y = 120

x = 120 - y

y = 120 - x

So,

a = 180 - 120 - y

a = 60 - y

b = 180 - 120 - x

b = 60 - x

Therefore,

Value of a and b is smaller or equal to 60°.
