That would be called a right triangle!
It is an isosceles triangle having 2 equal angles of 30 degrees and an apex angle of 120 degrees
You need the measures of two sides and for the triangle to be a right triangle to figure out the third side.
The triangle with angles measuring 40 degrees and 75 degrees is an acute triangle, as all its angles are less than 90 degrees. The third angle can be calculated as 180 - 40 - 75 = 65 degrees. With the side between the two given angles measuring 3 feet, this triangle is classified specifically as a scalene triangle, since all three sides will have different lengths.
No because the sum of the 2 smaller sides of a triangle must be greater than its longest side in order to construct a triangle.
A protractor is used for measuring angles and the 3 angles in a triangle add up to 180 degrees.
An acute angled scalene triangle.
60 degrees.
It is an isosceles triangle having 2 equal angles of 30 degrees and an apex angle of 120 degrees
The 3rd angle is 30 degrees and so it is an obtuse or a scalene triangle with 3 different side lengths and no right angle.
If two sides of a triangle are equal in length to the third side, then the triangle is equilateral, and all angles are 60 degrees.

With the side between the two given angles measuring 3 feet, this triangle is classified specifically as a scalene triangle, since all three sides will have different lengths.
An isosceles triangle has two sides with equal measures. The third side can be any length.
It is either a triangle on a curved surface or a polygon with 4 or more sides.
No because the sum of the 2 smaller sides of a triangle must be greater than its longest side in order to construct a triangle.
A protractor is used for measuring angles and the 3 angles in a triangle add up to 180 degrees.
Not always, but it is possible. An obtuse triangle has 1 angle which measures greater than 90 degrees. A scalene triangle has all different lengths in size. It is possible for a triangle to have different angles, with one above 90 degrees, and have all different side lengths.
