Triangle Similarity Theorems and Postulates

Front

What is the primary condition for two triangles to be considered similar according to the Angle-Angle Similarity Theorem?

Back

They must have two angles of the same measure.

Front

Are the triangles similar? If so, how?

Back

Not similar.

Front

What is the purpose of using one-point perspective in drawing?

Back

To create a 3D effect on a flat surface.

Front

Why does knowing two angles of a triangle allow you to determine the third angle?

Back

Because the sum of angles in a triangle is always 180 degrees.

Front

How many angles need to match in measure for two triangles to be similar by the Angle-Angle Similarity Theorem?

Back

Two.

Front

What does the Side-Angle-Side (SAS) Similarity Theorem state?

Back

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 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 sum of the interior angles of a triangle?

Back

180 degrees.

Front

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

Back

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

Front

What is a similarity ratio?

Back

The ratio of the lengths of corresponding sides of similar triangles.
