Question

Each angle in an equilateral triangle is .

• A. 45${}^{\circ }$
• B. 60${}^{\circ }$
• C. 75${}^{\circ }$

Answer 1

The correct option is B 60${}^{\circ }$

We know that,

• in an equilateral triangle, all sides are equal
• angles opposite to equal sides are equal
• sum of all angles of a triangle is 180${}^{\circ }$

Hence, all the angles in an equilateral triangle must be equal and the measure of each angle must be equal to 60${}^{\circ }$.
