Question

Part B

Now you will attempt to copy your original triangle using two of its angles:
• Draw a new line segment, DE, of any length and parallel to AB from AABC. You can draw DE
anywhere on the coordinate plane, but not on top of AABC.
.
• From point D, create an angle with the same measure as ZCAB. From point E, create an angle with
the same measure as ZABC.
• Draw rays from points D and E to E' and D' respectively to form the angles. Label the point of
intersection of the two rays F.
Draw ADEF by creating a polygon through points D, E, and F.
.
Record the measures of the angles of ADEF. Take a screenshot of your results, save it, and insert the
image below the table.

Answer 1

The student's task is to perform a geometric construction to create a triangle congruent to a given one by drawing parallel lines and replicating angles. The process involves drawing a line segment, constructing equal angles at its endpoints, drawing rays from these points and then taking measurements to confirm congruency.

Step-by-step explanation:

The student's problem involves geometric constructions to replicate a triangle using given angle measures and parallels. To perform the task, they must draw a line segment parallel to one side of the original triangle and construct angles equivalent to those in the original triangle from the new line's endpoints. By connecting the rays from these angles, they'll form a new triangle congruent to the original. In the context provided, which seems to be from a physics textbook, the student might be confused by references to vectors and components, given that the task at hand is a pure geometrical construction, more related to what one might encounter in a math class rather than physics.

Specific steps to follow for the construction:

1. Draw a line segment DE parallel to side AB of the original triangle.
2. Construct an angle equal to ∠CAB at point D and an angle equal to ∠ABC at point E.
3. Label the intersection of the two constructed rays as point F, completing triangle DEF.
4. Measure the angles within triangle DEF to ensure they match those from the original triangle.
