F24 Final Exam Review - Transformations & Similarity

Front

When you translate a point (x,y) by (x-3,y+6), how does the point move?

Back

The point moves 3 units left and 6 units up.

Front

What is the similarity statement for triangles ΔYZX and ΔNWE?

Back

ΔYZX~ΔNWE by AA.

Front

True or False: If two triangles are similar, they must have the same shape but not necessarily the same size.

Back

True.

Front

What is the scale factor from triangle ΔDEF to triangle ΔABC if the sides of ΔDEF are half the length of the corresponding sides of ΔABC?

Back

1/2.

Front

If two triangles are similar by SAS, what does SAS stand for?

Back

SAS stands for Side-Angle-Side.

Front

What is the definition of similar triangles?

Back

Similar triangles have the same shape but may differ in size; their corresponding angles are equal and their corresponding sides are proportional.

Front

How do you determine if two triangles are similar using the SSS method?

Back

If the ratios of the lengths of corresponding sides of two triangles are equal, then the triangles are similar by SSS.

Front

What does the AA criterion for triangle similarity state?

Back

If two angles of one triangle are equal to two angles of another triangle, then the triangles are similar by AA.

Front

If triangle ΔABC is similar to triangle ΔXYZ, what can be said about their corresponding angles?

Back

The corresponding angles of ΔABC and ΔXYZ are equal.

Front

What is the scale factor if triangle ΔPQR is enlarged to triangle ΔSTU and the lengths of the sides of ΔPQR are 3 and those of ΔSTU are 9?

Back

The scale factor is 3.
