Question

which statement is not true of line p?
it is a straight angle which measures 360°.
it stays the same even when the angles in the triangle change.
it combines the three angles from the triangle to form a straight line.
it represents the sum of the three angle measures of the triangle.

Explanation:

Step1: Recall straight angle measure

A straight angle measures \(180^\circ\), not \(360^\circ\) (a full circle is \(360^\circ\)).

Step2: Analyze other statements

• A straight line (formed by combining triangle angles) stays \(180^\circ\) regardless of triangle angle changes (since triangle angles sum to \(180^\circ\)).
• The three triangle angles combine to form a straight line (sum to \(180^\circ\)).
• The line represents the sum of the triangle's three angles (which is \(180^\circ\), a straight angle).

Answer:

It is a straight angle which measures \(360^\circ\).
