Unit 4 - Similar Triangles 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 their corresponding sides are in proportion.

Front

What is the Angle-Angle (AA) Similarity Postulate?

Back

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

Front

What is the Side-Side-Side (SSS) Similarity Theorem?

Back

If the corresponding sides of two triangles are in proportion, then the triangles are similar.

Front

What is the Side-Angle-Side (SAS) Similarity Theorem?

Back

If one angle of a triangle is congruent to one angle of another triangle and the sides including these angles are in proportion, then the triangles are similar.

Front

How do you find the missing side of similar triangles using proportions?

Back

Set up a proportion using the lengths of the corresponding sides of the triangles and solve for the missing side.

Front

What is a scale factor in dilation?

Back

The scale factor is the ratio of the lengths of two corresponding sides of similar figures. It determines how much the figure is enlarged or reduced.

Front

If triangle ABC is similar to triangle DEF, what can be said about their corresponding angles?

Back

The corresponding angles of triangle ABC and triangle DEF are equal.

Front

What is the formula for finding the area of a triangle?

Back

Area = 1/2 * base * height.

Front

How do you determine if two triangles are similar?

Back

You can determine if two triangles are similar by checking if they satisfy AA, SSS, or SAS similarity criteria.

Front

What is the relationship between the sides of similar triangles?

Back

The lengths of corresponding sides of similar triangles are proportional.
