Because the formula for finding the total interior angles of any polygon is;
(Number of sides - 2)*180 = sum of interior angles
A triangle has 3 sides so: (3 - 2)*180 = 180 degrees
A quadrilateral has 4 sides so: (4 - 2)*180 = 360 degrees
"The sum of the angles in a triangle equal 180 degrees" is a true statement.
Triangle.
No, because the angles of a triangle have to total 180 degrees and if there are three angles in a triangle, 90 * 3 cannot equal 180. To have three equal sides, the angles must equal 60 degrees 60 * 3 = 180.
A triangle is made up of 3 angles, which equal 180 degrees.
A triangle doesn't equal 180, but the sum of the internal angles of every triangle equals 180 degrees.
The three angles of a triangle are always equal to 180°, if not equal to 180° then it is not a triangle.
"The sum of the angles in a triangle equal 180 degrees" is a true statement.
The sum(addition) of the measures of the three angles of a triangle is 180 degrees.
180 degrees
Triangle.
A triangle with equal sides ia an equilateral triangle, in it all the internal are equal the sum of which is 180 degrees.
No, because the angles of a triangle have to total 180 degrees and if there are three angles in a triangle, 90 * 3 cannot equal 180. To have three equal sides, the angles must equal 60 degrees 60 * 3 = 180.
A triangle is made up of 3 angles, which equal 180 degrees.
A triangle doesn't equal 180, but the sum of the internal angles of every triangle equals 180 degrees.
A triangle with equal sides ia an equilateral triangle, in it all the internal are equal the sum of which is 180 degrees.
All angles in a triangle must equal 180, therefore 180 - 120 = 60
Yes the 3 interior angles of any triangle always add up to 180 degrees
