Triangle Similarity: AA, SSS & SAS — Easy Worksheet 2
Grade 10 · MathSheets Name: ____________________ Date: __________
Write AA, SSS or SAS if the triangles are similar, or not similar if they are not. Write scale factors as whole numbers or fractions.
How to solve
AA: two pairs of equal angles. SSS: all three pairs of corresponding sides have the same ratio. SAS: two pairs of sides have the same ratio and the angles between them are equal. Compare the ratios of corresponding sides (larger ÷ smaller); if they are not all equal, the triangles are not similar. The scale factor from △ABC to △DEF is DE/AB.
Example
Are the triangles similar? Write AA, SSS, SAS, or not similar.
