Parallel and Perpendicular Lines
Coordinate Plane
- Parallel lines have the same slopes
- Perpendicular Lines have opposite reciprocal slopes
- Writing the equation of a line
- Slope Intercept Form:
- y=mx+b
- need to know:
- slope (m)
- y-intercept (b)
- need to know:
- y=mx+b
- Point Slope Form
- y-y1=m(x-x1)
- need to know:
- slope (m)
- m=change in y/change in x
- might come from altitude
- m=change in y/change in x
- any point (x1,y1)
- might come from midpoint
- slope (m)
- need to know:
- y-y1=m(x-x1)
- Slope Intercept Form:
Transversal Relationships
- corresponding angles (1&5, 2&6, 3&7, 4&8)
- alt int angles (3&6, 4&5)
- alt ext angles (1&8, 2&7)
- consecutive int angles (3&5, 4&6)
- Consecutive ext angles (1&7, 2&8)
- consecutive int angles (3&5, 4&6)
- alt ext angles (1&8, 2&7)
- alt int angles (3&6, 4&5)
- IF lines m and n are parallel, then...
- congruent
- supplementary
- congruent
- corresponding angles (1&5, 2&6, 3&7, 4&8)
