Similar Triangles 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 their corresponding sides are in proportion.

What is the SAS similarity criterion for triangles?

Back

The SAS (Side-Angle-Side) similarity criterion 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.

What is the SSS similarity criterion for triangles?

Back

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

How can you determine if two triangles are similar using angle measures?

Back

If two angles of one triangle are equal to two angles of another triangle, then the triangles are similar (AA criterion - Angle-Angle similarity).

What is the relationship between the heights of two similar triangles?

Back

The heights of two similar triangles are proportional to the lengths of their corresponding bases.

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

Back

To find the height of an object using similar triangles, you can create a right triangle using a mirror or a shadow, and set up a proportion based on the similar triangles formed.

Front

What is the importance of the mirror method in measuring heights?

Back

The mirror method allows for indirect measurement of heights by using the properties of similar triangles, making it useful for measuring tall objects.

Front

What does it mean if two triangles are not similar?

Back

If two triangles are not similar, it means that their corresponding angles are not equal or their corresponding sides are not in proportion.

What is the significance of the term 'corresponding sides' in similar triangles?

Back

Corresponding sides are the sides of two triangles that are in the same relative position. In similar triangles, these sides are proportional.

How can you use proportions to find unknown side lengths in similar triangles?

Back

You can set up a proportion using the lengths of the corresponding sides of the similar triangles to solve for the unknown side length.
