Accelerated Math 2

 Two minor arcs are congruent if and only if their corresponding chords are congruent.

 Remember: A tangent is perpendicular to the radius  Also, if two tangents start at the same point, then they are congruent.

 If one chord is a perpendicular bisector of another chord, then the first chord is a diameter.  All of the following congruencies will be true:

 Arc Length is a partial circumference  Arc Length differs from Arc Measure in that it is measured in units (cm, ft, in……) Arc Measure is measured in degrees  Formula:

 Usually a shaded area, like a slice or multiple slices of pizza  Sector Area is a partial area  Formula:
