2. Congruence
Sign In
Congruent angles have matching arcs. Congruent sides have matching tick marks.
Corresponding Angles: ∠M ≅ ∠T, ∠N ≅ ∠S, and ∠O ≅ ∠V
Corresponding Sides: MN ≅ TS, NO ≅ SV, and OM ≅ VT
We want to write congruence statements comparing the corresponding parts in the given figures. To do so, we will use the matching arcs and tick marks to identify the corresponding parts.
