Answer:
The measure of an interior angle in a regular triangle is 60 degrees
Step-by-step explanation:
we know that
A regular triangle has three equal sides and three equal interior angles
Remember that the sum of the interior angles in a triangle must be equal to 180 degrees
so
Divide 180 by 3 to determine the measure of each interior angle
[tex]\frac{180^o}{3}=60^o[/tex]
A regular triangle is called equilateral triangle
therefore
The measure of an interior angle in a regular triangle is 60 degrees
