Use a protractor or if you know 2 of them then subtract these from 180 which will give you the 3rd angle because the 3 angles in any triangle always add up to 180 degrees.
the total of three angles is 180
Any three angles that sum to 180 can form a triangle.
A three-sided polygon is a triangle. The angles in a triangle add up to 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.
Yes the sum of the three angles in a triangle add up to 180 degrees.
the total of three angles is 180
Any three angles that sum to 180 can form a triangle.
All interior angles of a triangle MUST (a triangle by definition states that all interior angles MUST) add up to 180. Any measures would work, provided the three angles would add up to 180*....so a triangle with angles 1, 1, and 178 degrees works, as well as a triangle with 60, 60, and 60 degrees. Any angle combinations work, as long as the three angles add up to 180.
The three interior angles add up to 180°. (180° is the measure of a triangle)
Interior angles of a triangle have a sum of 180 degrees.
The 3 angles in any triangle add up to 180 degrees
A three-sided polygon is a triangle. The angles in a triangle add up to 180 degrees.
The three interior angles of any triangle add up to 180 degrees
Yes the sum of the three angles in a triangle add up to 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.
The sum(addition) of the measures of the three angles of a triangle is 180 degrees.
Yes, the sum of all the three interior angles of a triangle is 180o.
