Postulate 5: Angle Addition Postulate: If D is in the interior of angle ABC, then measure of angle ABC = measure of angle ABD + measure angle DBC. 

MEvery angle, except a straight angle, has exactly one bisector.

Question: Bisect this angle



answer:



Postulate 11 States that:

If two planes intersect, then their intersection is a line

> Practice Problem: > Identify the intersection between two planes. > > **Choices:** > A. Plane A > B. Plane B > C. Line CD > D. None of these > > > **Correct Answer: C** > **Solution:** > **Step 1:** Two planes are said to be in intersection if they cross in a single line. > **Step 2:** Here, line CD intersects the plane A and plane B shown in figure. > **Step 3:** Therefore, line CD is the intersection between the two planes.
