Triangle Similarity: Triangle Similarity Aa Sss Sas Worksheet Answers
Triangle similarity refers to the geometric relationship between two triangles that have the same shape but not necessarily the same size. In other words, similar triangles have proportional sides and congruent angles.
Criteria for Triangle Similarity
There are three main criteria for determining whether two triangles are similar:
- AA (Angle-Angle):If two triangles have two pairs of congruent angles, then the triangles are similar.
- SSS (Side-Side-Side):If the corresponding sides of two triangles are proportional, then the triangles are similar.
- SAS (Side-Angle-Side):If two triangles have two pairs of proportional sides and one pair of congruent angles between those sides, then the triangles are similar.
Triangle Similarity Worksheet
Exercise 1:Determine whether the following triangles are similar. Triangle ABC has sides AB = 5 cm, BC = 7 cm, and AC = 10 cm. Triangle PQR has sides PQ = 15 cm, QR = 21 cm, and PR = 30 cm.
Solution:Since the sides of triangle PQR are proportional to the corresponding sides of triangle ABC (15/5 = 3, 21/7 = 3, 30/10 = 3), the triangles are similar by the SSS criterion.
Exercise 2:Triangle XYZ has angles X = 30°, Y = 60°, and Z = 90°. Triangle MNO has angles M = 45°, N = 60°, and O = 75°. Are the triangles similar?
Solution:Since triangle XYZ and triangle MNO have two pairs of congruent angles (X = M and Y = N), the triangles are similar by the AA criterion.

Interactive Triangle Similarity Tool
An interactive online tool for exploring triangle similarity can be a valuable resource for students and educators. The tool should allow users to:
- Input the measurements of two triangles.
- Check whether the triangles are similar based on the AA, SSS, or SAS criteria.
- Display visual representations of the triangles and their properties, such as corresponding angles and proportional sides.
Such a tool can enhance understanding of triangle similarity and provide an interactive learning experience.
Essential Questionnaire
What is the AA Similarity Criterion?
The AA Similarity Criterion states that if two triangles have two pairs of congruent angles, then the triangles are similar.
How do I use the SSS Similarity Criterion?
The SSS Similarity Criterion states that if the three sides of one triangle are proportional to the three sides of another triangle, then the triangles are similar.
Can you explain the SAS Similarity Criterion?
The SAS Similarity Criterion states that if two sides of one triangle are proportional to two sides of another triangle, and the included angles are congruent, then the triangles are similar.
