Key Points:  

• Parallel Lines have equal slopes and never cross. 
• Perpendicular Lines have negative reciprocal slopes and they form right angles. 
• Vertical Angles are formed when two lines intersect.
• When 2 parallel lines are cut by a transversal,
  • Corresponding Angles are congruent.
  • Alternate Exterior Angles are congruent.
  • Alternate Interior Angles are congruent. 
    
• Sum of the angles of a Polygon = (n - 2)180
• Pythagorean Theorem ⇒ a² + b² = c²
  • Sum of the squares the legs of a right triangle equals the square of the hypotenuse 
• Perimeter - distance around a figure.
• Area of a Polygon
• Circumference - distance around a circle
• Area of a Circle
  
• Volume of Polyhedron/Sphere
  
• Coordinate Plane
• Slope - Rise/Run      m = (y₂ - y₁)/(x₂ - x₁)
  • Horizontal Lines have 0 slope.
  • Vertical Lines have no slope or undefined slope.  
    

Formulas:

• A=lw    A=½bh   A=bh    A= ½h(b1+b2)    A=s²     A=πr²
  
• V=lwh   V=Bh     V=πr²h     V= πr³      V=s³     C=2πr
