Show Answer Key & Explanations Step-by-step solution for: Similar Triangles Notes and Worksheets - Lindsay Bowden

▼

- Similar: same shape, different size
- Similar Triangles: triangles that have 3 pairs of congruent corresponding angles and 3 pairs of proportional/corresponding sides
*Reminder: Corresponding means in the same position*
*Proportional means the sides will have the same ratio*
- Therefore, △ABC ~ △DEF
- Examples:
1. △JKL ~ △MNO. Find all missing sides and angles.
- ∠L = 45°, ∠O = 45°, ∠N = 60°
- Side JL (q) = 9, Side MO = 3, Side NO (l) = 4.5
2. △QRS ~ △XYZ
Therefore...
- ∠Q ≅ ∠X
- ∠Y ≅ ∠R
- ∠RSQ ≅ ∠Z

Parent Tip: Review the logic above to help your child master the concept of triangle proportionality theorem worksheet answers.
