FLASHCARD QUESTION
Front
What does it mean for two triangles to be similar?
Back
Two triangles are similar if their corresponding angles are equal and their corresponding sides are in proportion.

FLASHCARD QUESTION
Front
What is the AA criterion for triangle similarity?
Back
The AA (Angle-Angle) criterion states that if two angles of one triangle are equal to two angles of another triangle, then the triangles are similar.

FLASHCARD QUESTION
Front
What is the SSS criterion for triangle similarity?
Back
The SSS (Side-Side-Side) criterion states that if the corresponding sides of two triangles are in proportion, then the triangles are similar.

FLASHCARD QUESTION
Front
What is the SAS criterion for triangle similarity?
Back
The SAS (Side-Angle-Side) criterion states 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.

FLASHCARD QUESTION
Front
How can you determine the height of an object using similar triangles?
Back
By setting up a proportion using the lengths of corresponding sides of similar triangles, you can solve for the unknown height.

FLASHCARD QUESTION
Front
If triangle ABC is similar to triangle DEF, what can be said about their angles?
Back
The corresponding angles of triangle ABC and triangle DEF are equal.
7.
FLASHCARD QUESTION
Front
If the sides of triangle ABC are 3, 4, and 5, and the sides of triangle DEF are 6, 8, and 10, are the triangles similar?
Back
Yes, triangle ABC and triangle DEF are similar by the SSS criterion because the sides are in proportion (3:6, 4:8, 5:10).
