Front

What is the definition of similar triangles?

Back

Similar triangles are triangles that have the same shape but may differ in size. Their corresponding angles are equal, and the lengths of their corresponding sides are proportional.

Front

If triangle A is similar to triangle B, what can be said about their corresponding angles?

Back

The corresponding angles of similar triangles are equal.

Front

What is the Side-Angle-Side (SAS) similarity criterion?

Back

The SAS similarity criterion states that 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

How do you find the value of x in a proportion?

Back

To find the value of x in a proportion, cross-multiply and solve for x.

Front

What is the formula for the area of a triangle?

Back

The area of a triangle is given by the formula: Area = 1/2 * base * height.

Front

What does it mean for two triangles to be congruent?

Back

Two triangles are congruent if they have the same size and shape, meaning all corresponding sides and angles are equal.

Front

If ΔSQR∼ΔSPT, what does this notation indicate?

Back

This notation indicates that triangle SQR is similar to triangle SPT.

Front

What is the definition of corresponding sides in similar triangles?

Back

Corresponding sides in similar triangles are the sides that are in the same relative position in each triangle.

Front

Back

Cross-multiply to get: 11(x - 5) = 7(x - 8). Simplifying gives x = -1/4.

Front

What is the relationship between the ratios of corresponding sides of similar triangles?

Back

The ratios of the lengths of corresponding sides of similar triangles are equal.
