Front

Sides that are in the same position in similar triangles are called

Back

Corresponding Sides

Front

What is the scale factor in similar triangles?

Back

The ratio of the lengths of corresponding sides of similar triangles.

Front

True or False: Sides in similar figures must be proportional.

Back

True

Front

If the scale factor is 4, what does it mean for the sides of the triangles?

Back

The sides of the larger triangle are 4 times the length of the corresponding sides of the smaller triangle.

Front

Line AB corresponds with what line in triangle XYZ?

Back

XY

Front

What is the relationship between corresponding angles in similar triangles?

Back

Corresponding angles are equal.

Front

If triangle ABC is similar to triangle DEF, and the length of side AB is 5 and side DE is 10, what is the scale factor?

Back

2

Front

What does it mean for two triangles to be similar?

Back

They have the same shape but may differ in size.

Front

If the scale factor is 0.25, how does it affect the size of the triangle?

Back

The sides of the new triangle are one-fourth the length of the original triangle.

Front

What is the formula to find the scale factor between two similar triangles?

Back

Scale Factor = Length of a side in the larger triangle / Length of the corresponding side in the smaller triangle.
