Question

Each angle of an equilateral triangle is: *

1 point

30°

90°

60°

45°​

Answer 1

60°

Step-by-step explanation:

1. We know that all angles and sides of equilateral triangle are equal.
2. Sum of all interior angles of triangle is 180°.

Let one angle of equilateral triangle be x

Then, All angles will be x (Beacuse All angles of equilateral triangle are equal).

So,

⇒ x + x + x = 180°

⇒3x = 180°

⇒x = 180°/3

⇒x = 60°

Thus, each angle of equilateral triangle will be of 60°.

More information:-

• If it is given that it is not a equilateral triangle then it's all angles and sides will not equal. That triangle may be Isosceles triangle or it may be scalar triangle.
• Isosceles triangle is a triangle. It's all sides are not Equal but it's two sides are equal. And the opposite angles of equal sides is also equal.
• Scalar triangle is a triangle. Its all sides are not equal. All are of different measure.
