Unit 4a Test Review

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 the lengths of their corresponding sides are proportional.

Front

What is the AA postulate for triangle similarity?

Back

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

Front

What is the SAS postulate for triangle similarity?

Back

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

Front

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

Back

To find the height of an object using similar triangles, set up a proportion based on the corresponding sides of the triangles formed by the object, the observer, and the ground.

What is the formula for finding the height of a geyser using a mirror?

Back

The height of the geyser can be found using the formula: Height = (Distance to geyser) * (Height of observer's eyes) / (Distance from observer to mirror).

Front

What is the definition of a similarity statement?

Back

Front

What does it mean if two triangles are similar?

Back

If two triangles are similar, it means their corresponding angles are equal and their corresponding sides are in proportion.

Front

What is the significance of the height of the observer in mirror problems?

Back

The height of the observer is crucial in mirror problems as it helps establish the proportions needed to find the height of the object being observed.
