Question

What is the measure of an interior angle in a regular triangle? Write your answer as an integer or as a decimal rounded to the nearest tenth.

Answer 1

The measure of an interior angle in a regular triangle is 60 degrees

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

`(180^o)/(3)=60^o`

A regular triangle is called equilateral triangle

therefore

The measure of an interior angle in a regular triangle is 60 degrees
