Lesson 4-2: Triangle Congruence – SSS, SAS, ASA, & AAS. Vocab SSS (side-side-side) congruence Included angle SAS (side-angle-side) congruence. Draw the following figures using a ruler. Draw a triangle, measure its lengths
SSS (side-side-side) congruence
SAS (side-angle-side) congruence
→ ∆’s congruent bySSS (side-side-side)
→ ∆’s congruent by SAS (side-angle
→ Look for SAS – list S or A in order
2. In ∆STN, which angle is included between
3. Which triangles can you prove congruent? Tell whether you would use the SSS or SAS Postulate.
4. What other information do you need to prove ∆DWO∆DWG?
5. Can you prove ∆SED ∆BUT from the information given? Explain.
