The angles given would form a right angle triangle
No because the angles given are applicable to a right angle triangle whereas an equilateral triangles has 3 interior angles each measuring 60 degrees.
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.
An obtuse angled isosceles triangle.
Yes because there are 3 interior angles in a triangle that add up to 180 degrees

40 degrees ! The internal angles of any triangle always total 180 degrees. Since you already know two angles (50 & 90) - the difference is 40.
The other acute angle in that triangle is 40 degrees.
A right triangle, whose the length measure of the side opposite to the angle of 30 degrees is one half of the length measure of the hypotenuse.
Yes an isosceles triangle can have two equal acute base angles of 40 degrees and an apex angle of 100 degrees
No. A triangle has 180 degrees, those only add up to 172. A right triangle has 1 right angle (an angle that is 90 degrees). The other 2 angles can be whatever combination of angles as long as they add up to 90 (such as 45 and 45) since a triangle has 180 degrees.

An isosceles triangle has two equal side and angle measurements.
Scalene
It can. An example of an isosceles triangle without any angles greater than 90 would be an equilateral triangle, with all angles equalling 60 degrees. An example with an angle greater than 90 would be a triangle with angles of 100 degrees, 40 degrees and 40 degrees. You couldn't have an isosceles triangle with 2 angles greater than or equal to 90, as all the angles sum to 180 degrees.
The sum of the angles is 180 degrees in any triangle. So 180-140 is 40 and the third angle is 40 degrees.
