Write a paragraph proof of the Triangle Angle Sum Theorem using the following figure. A line should pass through F as part of th
BabaBlast [244]

Answer:

Step-by-step explanation:

To prove the triangle angle sum theorem,

We will do a construction by drawing a line PQ passing through point F and parallel to line DE.

                Statements                              Reasons

1). ∠PFD + ∠QFD = 180°                     1). linear pair postulate

2). ∠QFD = ∠QFE + ∠EFD                 2). Angle addition postulate

3). ∠PFD + ∠QFE + ∠EFD = 180°       3). Substitution property

4). ∠PFD ≅ ∠FDE                               4). Alternate interior angles

    ∠QFE ≅ ∠DEF                                

5). ∠FDE + ∠DEF + ∠EFD = 180°       5). Substitution property

Hence sum of interior angles of ΔDEF is 180°.

Point E is located at (–5, 2). Point M is the reflection of point E across the y-axis. What is the distance between E and M?
Lisa [10]
The distance between E and M will be twice the distance from either to the y-axis. That distance is given by their x-coordinates.

The distance between E and M is 10 units.
