Back

SSS

To find the height of a very tall pine tree, you place a mirror on the ground and stand where you can see the top of the pine tree. If the distance from the mirror to the tree is 144 feet and your eye level is 72 feet, how tall is the tree?

Back

72 feet

Determine whether the triangles are similar by AA~, SSS~, SAS~, or not similar. If the angles of two triangles are not equal, what can we conclude about their similarity?

Back

Not Similar

Front

What is the definition of similar triangles?

Back

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

Front

What does AA similarity criterion state?

Back

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

Front

What does SSS similarity criterion state?

Back

If the sides of one triangle are proportional to the sides of another triangle, then the triangles are similar.

Front

What does SAS similarity criterion state?

Back

If two sides of one triangle are proportional to two sides of another triangle and the included angle is equal, then the triangles are similar.

Front

If two triangles have one angle equal and the sides including that angle are proportional, what can be concluded?

Back

The triangles are similar by SAS.
