The triangle angle sum property states that the measures of the 3 angles of any triangle must add to 360 degrees.
serg [7]

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 :

(n-2)180

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

(3-2) 180

= 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.
