Title: Similar Triangles


1
Similar Triangles
2
Similar Triangles
  • Similar triangles have
  • Congruent corresponding angles
  • Sides that are in a direct ratio

3
Triangle Similarity Theorems
  • You can conclude that two triangles are similar
    if
  • AA two pairs of corresponding angles
    are congruent

4
Triangle Similarity Theorems
  • You can conclude that two triangles are similar
    if
  • SSS all three pairs of sides are in the same
    proportion

5
Triangle Similarity Theorems
  • You can conclude that two triangles are similar
    if
  • SAS two pairs of sides are in the same
  • proportion and their included angles
    are congruent
