No, an obtuse angle and an acute angle cannot combine to form a straight angle. An obtuse angle measures more than 90 degrees, while an acute angle measures less than 90 degrees. The sum of these two angles would exceed 180 degrees, which is the measure of a straight angle. Therefore, they cannot combine to create a straight angle.

Is the supplement of an acute angle a obtuse angle?
yes. the supplement adds to the acute angle to make 180 degrees. An acute angle is less than 90 degrees. Example: acute angle is 30 degrees. 180-30 is 150, which is obtuse.
Can you make a triangle with 1 obtuse angle 1 acute angle and 1 right angle?
No.
Are the exterior angles of a scalene triangle always obtuse?
No, they are not always obtuse, because a scalene triangle can also sometimes be an obtuse triangle (meaning that one interior angle is obtuse), making one exterior angle acute. Scalene triangles also can be a right triangles (meaning that one interior angle is a right angle), which would make an exterior angle a right angle. Then also they can be acute triangles, in this case all 3 exterior angles are obtuse.
How do two intesecting line but not perpendicular look?
They make a pair of acute angles and a pair of obtuse angles. In rotational order, the angles are acute, obtuse, acute, obtuse.
How do you make a abtuse angle?
You can construct an obtuse angle with a straight edge and a protractor and that the angle must be greater than 90 degrees but less than 180 degrees.
