What is the Triangle Proportionality Theorem?

Back

The Triangle Proportionality Theorem states that if a line is drawn parallel to one side of a triangle, it divides the other two sides proportionally.

Front

What does SAS similarity stand for?

Back

SAS similarity stands for Side-Angle-Side similarity, which 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

What is AA similarity?

Back

AA similarity stands for Angle-Angle similarity, which states that if two angles of one triangle are equal to two angles of another triangle, then the triangles are similar.

Front

What is SSS similarity?

Back

SSS similarity stands for Side-Side-Side similarity, which states that if the three sides of one triangle are proportional to the three sides of another triangle, then the triangles are similar.

Front

How do you find the missing length in similar triangles?

Back

To find the missing length in similar triangles, set up a proportion using the lengths of the corresponding sides and solve for the unknown.

Front

What is the formula for setting up a proportion in similar triangles?

Back

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 and their corresponding sides are not proportional.

Front

What is the significance of the included angle in SAS similarity?

Back

The included angle in SAS similarity is crucial because it must be equal for the triangles to be considered similar.

Front

How can you determine if triangles are similar using AA?

Back

To determine if triangles are similar using AA, check if two angles of one triangle are equal to two angles of another triangle.

Front

What is the relationship between the sides of similar triangles?

Back

The sides of similar triangles are in proportion, meaning the ratios of the lengths of corresponding sides are equal.
