HYKwM-CH02-S20-SimilarTriangles[F]

Angles in similar triangles that have the same size.

• Corresponding angles
• Rearrange
• Alternate interior angles
• Complementary angles

When two triangles have two pairs of corresponding sides that are in the same ratio and the angles between these sides are equal, the triangles are similar.

• Side-angle-side similarity
• Triangle angle bisector theorem
• Isolate
• Side-side-side similarity

If the ratio between the hypotenuses of two right triangles is the same as the ratio between another pair of corresponding sides, then the triangles are similar.

• Side-angle-side similarity
• Angle-angle similarity
• Right-angle, hypotenuse, side similarity
• Isolate

To perform the operation of splitting into equal parts or groups.

• Multiply
• Cross-multiply
• Divide
• Simplify

To perform the operation of repeated addition.

• Divide
• Multiply
• Quotient
• Multiplication

When two triangles have three pairs of corresponding sides that are in the same ratio, then the triangles are similar.

• Side-side-side similarity
• Missing sides
• Isolate
• Corresponding angles

To change the order or position of something.

• Rearrange
• Divide
• Compose
• Corresponding Angles

A transformation that creates similar triangles by making bigger or smaller copies of a triangle.

• Scale Factor
• Enlargement
• Reduction
• Proportion

When two triangles have two equal angles, all their corresponding angles are equal, so the triangles are similar.

• Exterior angle of a triangle
• Isolate
• Side-angle-side (sas)
• Angle-angle similarity

The quantitative relationship between two quantities, often expressed as a fraction or decimal.
