Proving Triangles Similar

Determine if the triangles are similar. If so, state the similarity postulate or theorem.

• AA~

• SSS~

• SAS~

• The triangles are not similar.

Which method can be used to show that the two triangles at the right are similar?

• AA~

• SSS~

• SAS~

• Cannot be shown

Are these two triangles similar and if so, identify the correct similarity statement.

• AA~

• SSS~

• SAS~

• None of these

Decide whether the triangles are similar. If so, write a similarity statement.

• ΔABC ~ ΔFED

• ΔABC ~ ΔDEF

• ΔABC ~ ΔDFE

• The triangles are not similar.

How are these two triangles similar? Solve for y.

• AA~, 32

• AA~, 9.6

• SAS~, 9.6

• SAS~, 4

• SAS~, 96

In the diagram, ΔMNP ~ ΔRST. Find the value of x.

• 20

• 24

• 30

• 32

Use the information in the diagram to determine the height of the tree.

• 264 feet

• 60 feet

• 72 feet

• 80 feet

Determine if the triangles are similar and if they are, what postulate proves them to be similar.

• Not Similar

Determine if the triangles are similar and if they are, what postulate proves them to be similar.

• Not Similar

Determine if the triangles are similar and if they are, what postulate proves them to be similar.

• Not Similar
