Front

What does it mean for triangles to be similar?

Back

Triangles are similar if their corresponding angles are equal and their corresponding sides are in proportion. This can be established using criteria such as AA (Angle-Angle), SSS (Side-Side-Side), or SAS (Side-Angle-Side).

Front

What is the AA similarity criterion?

Back

The AA (Angle-Angle) similarity criterion states that if two angles of one triangle are equal to two angles of another triangle, then the triangles are similar.

Front

What is the SSS similarity criterion?

Back

The SSS (Side-Side-Side) similarity criterion states that if the corresponding sides of two triangles are in proportion, then the triangles are similar.

Front

What is the SAS similarity criterion?

Back

The SAS (Side-Angle-Side) similarity 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.

Front

What is the ASA similarity criterion?

Back

The ASA (Angle-Side-Angle) similarity criterion states that if two angles and the included side of one triangle are equal to two angles and the included side of another triangle, then the triangles are similar.

Front

What is the HL theorem in triangle similarity?

Back

The HL (Hypotenuse-Leg) theorem states that if the hypotenuse and one leg of a right triangle are equal to the hypotenuse and one leg of another right triangle, then the triangles are similar.

Front

How do you find the length of the hypotenuse in a 45-45-90 triangle?

Back

Front

What is the relationship between the angles in a triangle?

Back

The sum of the interior angles in any triangle is always 180 degrees.
