What are the two steps to rotation a figure 90/270 degrees?

1. Swap x and Y

2. Apply the properties of the new quadrant 

300

What do we mean when we say angels are supplementary?

They add to equal 180

300

A triangle has two known angle measures, 25 and 90. What is the third angle measures of the triangle?

65 degrees

How would you describe a linear pair? And are they congruent or supplementary? 

Angles right next to each other and add to euqual 180

Supplementary
