The correct statement is that in the condition when the angle C is increases, the middle section of the line p increases to form a right-angled triangle.
In other case, where the angle C decreases, the middle section of the line p decreases to become a right angle at exactly ninety degrees.
What are Triangles?
Triangles are the ones that have three sides formed at different angles such that their area is not more than and equal to 270 degrees.
In this example, it is observed that the line p has three angles with one angle being an acute angle and the other being an obtuse angle, and a straight lined angle at 180 degrees.
When angle C, which is an acute angle increases the middle section, intersects the line p to become a right angle.
A similar condition is seen when the decrease in the angle of obtuse angle results in the decrease in the angle to become a right angle.
Hence, the correct statements for both the conditions are as explained above.
