2. PARTS OF SIMILAR TRIANGLES
• How can I use proportional perimeters of similar
triangles?
• How can I use proportionality to find altitudes of
similar triangles?

3. THEOREM 6.7
Proportional Perimeters Theorem: If two triangles are similar, their
perimeters have the same proportion as the corresponding sides

5. SPECIAL SEGMENTS
Altitude: A segment from a vertex to the line containing the opposite side
and perpendicular to the line containing that side

6. THEOREM 6.8
