They equal 180 degrees.
In an isosceles triangle, two angles are equal. Since the angles provided are 54 degrees and 63 degrees, the equal angles must be 54 degrees. The sum of the angles in any triangle is 180 degrees. Thus, the measure of the third angle is calculated as follows: 180 - 54 - 54 = 72 degrees.
The interior angles of any triangle (not traingle) always sum to 180 degrees. Whether or not it is equilateral (not eguilateral) is irrelevant.
If triangle has one obtuse angle other two angles are acute. Since, sum of angles of triangle is 180.
A triangle is a closed shape with 3 straight lines, where the sum of its angles is 180 degrees.
The sum of the three constitutive angles of a planar triangle is always equal to 180 degrees or two right angles. And there are two things in it as well. they are diagonal and a exterior angle
No matter what, all three angles of the triangle will ALWAYS add up to 180 degrees.
The sum of the angles in any triangle is 180 degrees.
The sum of the interior angles on an Obtuse Triangle is 1800 . This is true of ALL triangles.
True the 3 interior angles of any triangle always add up to 180 degrees
"The sum of the angles in a triangle equal 180 degrees" is a true statement.
The sum of the interior angles of ANY triangle is 180 degrees.
360 degrees (this is true with any convex polygon)
90° . That's true of any triangle. Doesn't have to be isosceles.
The sum of the three angles of any triangle is 180o.
The sum of the angles in ANY triangle (equiangular or not) is 180 degrees.
The sum of the 3 angles in any triangle including a scalene triangle add up to 180 degrees.
The sum of the angles inside a triangle is 180 degrees.
