Matching angles are called

Corresponding Angles

Front

Find the missing side length given that the triangles are similar: If Triangle A has sides 3, 4, and x, and Triangle B has sides 6, 8, and 9, what is x?

Back

9

Front

The 2 shapes are similar. Solve for X: If Triangle A has sides 2 ft, 3 ft, and X, and Triangle B has sides 4 ft, 6 ft, and 6 ft, what is X?

Back

2 ft

Front

Determine whether the triangles are similar by AA~, SSS~, SAS~, or not similar: Triangle A has angles 30°, 60°, and 90°; Triangle B has angles 30°, 60°, and 90°. How are they similar?

Back

AA

Front

Are the triangles similar? Triangle A has sides 3, 4, 5 and Triangle B has sides 6, 8, 10. Yes or No?

Back

No

Front

What is the definition of similar triangles?

Back

Triangles that have the same shape but not necessarily the same size; their corresponding angles are equal and their corresponding sides are in proportion.

Front

What does SSS stand for in triangle similarity?

Back

Side-Side-Side; a criterion for triangle similarity stating that if the corresponding sides of two triangles are in proportion, then the triangles are similar.

Front

What does AA stand for in triangle similarity?

Back

Angle-Angle; a criterion for triangle similarity stating that if two angles of one triangle are equal to two angles of another triangle, then the triangles are similar.

Front

What does SAS stand for in triangle similarity?

Back

Side-Angle-Side; a criterion for triangle similarity stating that if two sides of one triangle are in proportion to two sides of another triangle and the included angles are equal, then the triangles are similar.

Front

If two triangles have sides in the ratio 2:3, are they similar?

Back

Yes, if the corresponding angles are also equal.
