Q. 15
If two angles of a triangle are 60° each, then the triangle is
A. Isosceles but not equilateral
B. Scalene
C. Equilateral
D. Right-angled
Answer :
If 2 angles of triangle is 60°
Then;
60° + 60° + x = 180°
120° + x = 180°
x = 180° - 120°
x = 60°
∴ All angles are equal to 60°
Hence it is a equilateral triangle
