What is the criteria for two triangles to be similar?
Corresponding angles are congruent and corresponding sides are proportional.
Opposite angles are congruent and opposite sides are proportional.
Adjacent angles are congruent and adjacent sides are proportional.
Equal area and equal perimeter.
What is the difference between congruency and similarity?
Congruency is used for 2D shapes, while similarity is used for 3D shapes.
Congruency and similarity are the same concept.
Congruency involves only shape being equal, while similarity involves both shape and size being equal.
Congruency involves both shape and size being equal, while similarity involves only shape being equal.
How can you prove two triangles are congruent?
By measuring the area of each triangle
By showing that all corresponding sides are equal in length and all corresponding angles are equal in measure.
By comparing the colors of the triangles
By counting the number of sides
Explain the concept of scale factor in similarity.
The scale factor in similarity is the ratio of the lengths of corresponding sides of two similar figures.
The scale factor is the sum of corresponding sides of similar figures.
Scale factor is the area of the larger figure divided by the area of the smaller figure.
Scale factor is the angle between corresponding sides of similar figures.
