An obtuse triangle
An obtuse angle
It is an obtuse triangle if its 2 other acute angles are different in sizes.
Obtuse Angle
any triangle can contain at most 1 obtuse angle. it is called an obtuse triangle.
Every triangle must have at least two acute angles. The third one can be acute, right (90 degrees), or obtuse.
An obtuse angle
Types of triangle ; EQUILATERAL all three sides the same length and all three angles are 60 degrees. ISOSCELES Two sides the same length and two angles have the same degrees value. RIGHT-ANGLED All three sides can be of different lengths. However, it MUST have one Right-Angle (90 degrees) SCALENE All three sides of different lengths and all three angles of different angular values. NB In ALL four cases the sum of the interior angles MUST ADD TO 180 DEGREES.

It is an obtuse scalene triangle
Right angle (90) Acute angle (<90) Obtuse angle (>90) Straight angle (180) Reflex angle (>180)
An obtuse angled triangle.
well... first you must say what kind of triangle it is whether its isisceles or anything else and then meausre the angle and there you go. ex. acute obtuse equalateral triangle.
All triangles have 3 sides and 3 interior angles that add up to 180 degrees and they are classed as follows:- 1 Scalene triangle has 3 acute angles of different sizes 2 Right angle triangle has a 90 degree angle and 2 acute angles 3 Obtuse triangle has an obtuse angle and 2 acute angles 4 Isosceles triangle has 2 equal angles plus another angle 5 Equilateral triangle has 3 equal 60 degee angles
