An obtuse angle is an angle measuring between 90 and 180 degrees
A right angle triangle has 2 acute angles that add up to 90 degrees, along with 1 right angle of 90 degrees.
An isosceles triangle has two equal angles and one different angle. The sum of the angles in any triangle is always 180 degrees. Therefore, the two equal angles in an isosceles triangle must add up to 180 degrees minus the different angle. So, each of the two equal angles in an isosceles triangle measures (180 - x) / 2 degrees.
Any number from 1 to 178 degrees, on a flat surface. * * * * * The correct answer is any number in the open interval (0, 180). An angle can be 0.0001 degrees or 179.9999 etc.
Smallest possible interior angle of regular polygon is 60 degrees (triangle). The greater the number of sides, the greater each interior angle. If exterior angle is 30 degrees, the polygon has 12 sides.
The sum of the angles of a triangle is 180 degrees. So we have: 80 + 60 = 140 degrees, the sum of the two angles of the triangle 180 - 140 = 40 degrees, the measure of the third angle. Thus the measure of the third angle is 40 degrees.
The sum of the angles in a triangle equals 180, so the third angle is forty degrees. JTPaulson

Because the sum of the interior angles of a triangle must equal 180 degrees, the third angle must equal 180-80-60 = 40 degrees.
180 - ( 80 + 60 ) = 40 the answer would be 40 degrees
The total degrees of all three angles in any triangle must equal 180 drgrees. Therefor the third angle must be 40 degrees (80+60+40=180). Ans by Allen Rice
180 - (80 + 60) ie 40

The three angles of a triangle add to 180 degrees. If two of them add to 140 degrees then the third must be 180 - 140 = 40 degrees.
There is 180 degrees in every triangle.
