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:
