What is the Segment Addition Postulate?

• It states that the sum of the angles in a triangle is 180 degrees.

• It states that if a point is between two other points on a line, the sum of the two smaller segments equals the larger segment.

• It states that the sum of the interior angles of a polygon is equal to the number of sides minus two times 180 degrees.

• It states that the sum of the lengths of two sides of a triangle is greater than the length of the third side.

In the Segment Addition Postulate, what must be true about the points?

• They must be non-collinear.

• They must form an equilateral triangle.

• They must form a right angle.

• They must be collinear.

In Example 3, if AB = 12 and CD = 13, are AB and CD congruent?

• No, because they are not parallel.

• Yes, because they are on the same line.

• No, because their lengths are different.

• Yes, because they are both segments.
