An obtuse angled isosceles triangle.
The other 2 angles measure 40 degrees each. In an isosceles triangle two angles are the same and the third is different. However, the angles in the triangle must add up to 180. If the 100 degree angle was one of the 2 identical angles, then the angles in the triangle would add up to more than 200 Because of this the 100 degree angle must be the different angle. 180-100=80 80/2=40 Therefore the other angles are each 40 degrees (Perhaps not the most eloquent answer but it's the general gist)
Yes you can.
An acute angled scalene triangle.
Since a right triangle has 180 degree angles in it, you know 2 angles already. One is the 90 degree angle, since the triangle is a right one. The other is 40 degrees, as in your statement. 90 plus 40 is 130. 50 degrees is the missing angle since 50 + 40+ 90 equal 180 degrees. Hopefully that helped you.
100 degree, 40 degree and 40 degree.
An obtuse angled isosceles triangle.
40 degrees
Sure. That leaves 100 degrees for the third angle. A fine-looking triangle.
Good luck trying to draw this one ! Any two sides of a triangle are greater that the third; 40+40<100, so no triangle.
40 degrees each
If it is an isosceles triangle then the missing side is 40 cm but for any triangle the sum of its two smaller sides must be greater than its longest side.
It depends on what is known about the triangle.

180 degrees - 100 degrees - 40 degrees = 40 degrees
