Step-by-step explanation:
Answer: False
Step-by-step explanation:
Triangle is a polygon with 3 sides. The formula for calculating the sum of angle in a polygon is given as :

where n is the number of sides , so to calculate the sum of angles in a triangle we have :

= 1 x 180
= 180
Therefore : The triangle angle sum property states that the measures of the 3 angles of any triangle must add to 180 degrees.
