Unit 8 Similar Triangles Retest

Front

What does AA ~ Theorem state about triangle similarity?

Back

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

Front

What does SAS ~ Theorem state about triangle similarity?

Back

If two sides of one triangle are in proportion to two sides of another triangle and the included angle is equal, then the triangles are similar.

Front

What does SSS ~ Theorem state about triangle similarity?

Back

If the three sides of one triangle are in proportion to the three sides of another triangle, then the triangles are similar.

Front

How can you determine if two triangles are not similar?

Back

If none of the AA, SAS, or SSS conditions are met, the triangles are not similar.

Front

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

Back

The corresponding angles of similar triangles are equal.

Front

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

Back

The corresponding sides of similar triangles are in proportion.

Front

If angle A = 50° and angle B = 50°, what can be concluded about triangle ABC and triangle DEF if angle C = angle F?

Back

Triangle ABC is similar to triangle DEF by AA ~ Theorem.

Front

If two triangles have sides of lengths 3, 4, and 5 and 6, 8, and 10, are they similar?

Back

Yes, they are similar by SSS ~ Theorem because the sides are in proportion (3:6 = 1:2, 4:8 = 1:2, 5:10 = 1:2).

Front

If triangle ABC has sides of lengths 5, 12, and 13, and triangle DEF has sides of lengths 10, 24, and 26, are they similar?

Back

Yes, they are similar by SSS ~ Theorem because the sides are in proportion (5:10 = 1:2, 12:24 = 1:2, 13:26 = 1:2).

Front

If triangle ABC has angles of 30°, 60°, and 90°, what type of triangle is it?

Back

It is a right triangle.
