Chapter 3 Flashcards
What are interior angles?
Angles inside
What are exterior angles?
Angles outside
What are alternate interior angles?
Angles made between the two intersecting lines that are opposite sides of the transversal
What are same side interior angles?
Also known as consecutive interior angles; same side of transversal and interior angles
What are corresponding angles?
Lie on the same side of the transversal and in corresponding positions
What are alternate exterior angles?
Lie and exterior area and are on opposite sides of the transversal
All of the types of angles are congruent except…?
Same side interior angles; they are supplementary
What is the slope?
“Rise over run”
What is the slope intercept form?
y=mx+b
What is the point slope form?
y-y1=m(x-x1)
What is the standard form?
Ax+By=C
What is a parallel slope?
Same slope
What is perpendicular slope?
Opposite slope
What do all angles in a triangle add up to?
180
What is the exterior angle of a polygon?
Formed by a side and an extension of an adjacent side of the polygon
What is the exterior angle theorem?
The measure of each exterior angle of a triangle is equal to the sum of the measures of its to nonadjacent angles
What is a transversal?
Intersects two or more lines
