Question

Plz help me if you can

Answer 1

Answer:

Answer One - Angles forming a linear pair sum to 180

Answer Two - Substitution

Answer Three - Definition of perpendicular lines

Step-by-step explanation:

<SWT and <TWU are supplementary because together they make a straight line, which is a 180-degree angle. When supplementary angles are added together they equal 180. Therefore the reason is "angles forming a linear pair sum to 180"

Then, <TWU is replaced with <SWT. Since they are equal they can be substituted for each other.

The definition of a perpendicular angle is when two lines which meet at a right angle, which is 90 degree. Therefore, TV and SU are perpendicular.
