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 a triangle's angles will always equal 180 degrees?
"The sum of the angles in a triangle equal 180 degrees" is a true statement.
What polygon is equal to 180 degrees?
Triangle.
If a triangle has 1 right angle can it have three equal sides how?
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.
What is the difference between an angle and a triangle?
A triangle is made up of 3 angles, which equal 180 degrees.
Do all triangles equals 180?
A triangle doesn't equal 180, but the sum of the internal angles of every triangle equals 180 degrees.
The triangles sum says that the 3 angle in a triangle always equal 180?
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 a triangle's angles will always equal 180 degrees?
"The sum of the angles in a triangle equal 180 degrees" is a true statement.
Is the perimeter of a triangle equal 180?
The sum(addition) of the measures of the three angles of a triangle is 180 degrees.
What does the perimeter have to equal in a triangle?
180 degrees
What polygon is equal to 180 degrees?
Triangle.
A triangle with three equal sides?
A triangle with equal sides ia an equilateral triangle, in it all the internal are equal the sum of which is 180 degrees.
If a triangle has 1 right angle can it have three equal sides how?
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.
What is the difference between an angle and a triangle?

Do all triangles equals 180?
A triangle doesn't equal 180, but the sum of the internal angles of every triangle equals 180 degrees.
What is a triangle has three sides of equal length?
A triangle with equal sides ia an equilateral triangle, in it all the internal are equal the sum of which is 180 degrees.
Two angle in a triangle equal 120 What is the measure of the third angle?
All angles in a triangle must equal 180, therefore 180 - 120 = 60
What type of triangle is equal to 180 degrees?
The 3 interior angles of any triangle add up to 180 degrees
