Question

1. choose the best answer. what is a figure formed by two rays with a common endpoint? collinear angle bisector angle addition postulate angle 8. choose the best answer. if s is in the interior of ∠pqr, then m∠pqs + m∠sqr = m∠pqr. angle addition postulate protractor postulate angle bisector angle

Explanation:

Question 7

• "collinear" refers to points on a straight line, not a figure with two rays.
• "angle bisector" is a ray that divides an angle into two equal parts, not the figure itself.
• "Angle Addition Postulate" is a rule about angle measures, not a figure.
• An "angle" is defined as a figure formed by two rays with a common endpoint.

• The "Angle Addition Postulate" states that if a point (S here) is in the interior of an angle (∠PQR), then the sum of the measures of the two smaller angles (∠PQS and ∠SQR) equals the measure of the larger angle (∠PQR).
• "Protractor Postulate" is about assigning numbers to angle measures with a protractor.
• "angle bisector" divides an angle into two equal angles, not related to this sum.
• "angle" is the figure, not the postulate about its measure sum.

Answer:

D. angle
