RafaNo, the angles 40 degrees, 60 degrees, and 80 degrees do not make a triangle because the sum of the interior angles of a triangle must be 180 degrees. In this case, the sum of the angles 40 degrees, 60 degrees, and 80 degrees is 180 degrees, which means they lie on a straight line and do not form a closed triangle.

What triangle has the angles 40 50 and 90 degrees?
The triangle with angles measuring 40, 50, and 90 degrees is a right triangle. In a right triangle, one of the angles is always 90 degrees, making it a right-angled triangle. The other two angles are acute angles, measuring less than 90 degrees each. The sum of the interior angles of any triangle is always 180 degrees.
A triangle has one angle of 80 degrees an another of 60 degrees how many degrees must there be in the third angle?
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.
What type of triangle has interior angles with measures of 30 and 40?
The 3rd angle has to be 110 degrees therefore it is an obtuse triangle
An isosceles triangle has two angles that each measure 40 degrees what is the measure of the third angle?
A triangles angles have to add up to 180 degrees so since there are two angles that measure 40 it is 180-80=100(answer.)
Is is possible for an isosceles triangle to be an acute triangle?
Yes, but a triangle is acute only if all three of its angles are acute (< 90o).An isosceles triangle can be an acute triangle, but it doesn't have to be.An acute triangle can be an isosceles triangle, but it doesn't have to be.That depends on the sizes of its angle because an isosceles triangle has 2 equal sides and 2 equal angles which could be 70 degrees, 70 degrees and 40 degrees which are all acute angles that add up to 180 degrees.
