It is a scalene triangle other than a right angle triangle
A right angle triangle or an isosceles triangle.
To circumscribed a circle about a triangle you use the angle. This is to get the right measurements.
It is an obtuse triangle
i depends of the lengths of the sides
An isosceles triangle has two equal side and angle measurements.
It will be a right angled triangle with angles of 90, 72 and 18 degrees.
Each exterior angle measures 120 degrees
Those wouldn't be angle measurements, they would be sides. A triangle could be constructed with sides of those lengths.
use a protractor.
The triangle with angle measurements of 137 degrees, 17 degrees, and 26 degrees cannot exist because the sum of the angles in any triangle must equal 180 degrees. In this case, 137 + 17 + 26 equals 180 degrees, which is valid, but the angle of 137 degrees indicates it is an obtuse triangle. Thus, the triangle is classified as an obtuse triangle.
