Question

3. Show that the angles of an equilateral triangle
arc 60° each​

Answer 1

Answer:

Step-by-step explanation:

we know that angles of a equilateral triangle are same

sum of angles of a triangle is 180 degree

a triangle has 3 sides

so each side must be 60 degree

Answer 2

Answer:

Sum of all angles in a triangle:

180°

since an equilateral triangle has all sides and angles equal:

let us assume the angles are x

so,

3x = 180

x = 180÷3

x = 60°

3x is assumed as all sides are equal in an equilateral triangle
