Geometry Honors TNReady Flashcard 2

Front

What is the AA similarity postulate?

Back

The AA (Angle-Angle) similarity postulate states that if two angles of one triangle are equal to two angles of another triangle, then the triangles are similar.

Front

What is the SSS similarity theorem?

Back

The SSS (Side-Side-Side) similarity theorem states that if the corresponding sides of two triangles are in proportion, then the triangles are similar.

Front

What is the SAS similarity theorem?

Back

The SAS (Side-Angle-Side) similarity theorem states that if two sides of one triangle are in proportion to two sides of another triangle and the included angles are equal, then the triangles are similar.

Front

How do you determine if triangles are similar?

Back

Triangles can be determined to be similar by using the AA, SSS, or SAS postulates.

Front

What is the definition of similar triangles?

Back

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

Front

If two angles of one triangle measure 45° and 55°, what are the measures of the angles of a similar triangle?

Back

The measures of the angles of a similar triangle would also be 45° and 55°.

Front

What is the relationship between the sides of similar triangles?

Back

The lengths of the corresponding sides of similar triangles are proportional.

Front

How can you find the height of an object using similar triangles?

Back

You can use the properties of similar triangles to set up a proportion between the height of the object and the lengths of the corresponding sides.

Front

What is the formula for finding the height of a tree using similar triangles?

Back

Height of tree = (Height of shadow / Length of shadow) * Length of tree's shadow.

Front

What is the significance of the angles in determining triangle similarity?

Back

The angles are significant because if two angles are equal, the third angle must also be equal, confirming triangle similarity.
