Similar Figures

Front

Two objects that are the same shape but not the same size are _______.

Back

Similar

Front

All angles in similar figures are congruent. True or False?

Back

True

Front

Are these triangles similar? (Provide reasoning)

Back

Yes, they are similar because their corresponding angles are equal and their sides are proportional.

Front

Are these figures similar? (Provide reasoning)

Back

No, they are not similar because their corresponding side lengths are not proportional.

Front

Tell whether the two figures are similar. Explain your reasoning. (Hint: are they proportional?)

Back

No, not similar because they are the same shape, but side lengths are not proportional.

Front

What is the definition of similar figures?

Back

Similar figures are shapes that have the same shape but may differ in size, with corresponding angles being equal and corresponding sides being proportional.

Front

If two triangles have angles measuring 30°, 60°, and 90°, are they similar?

Back

Yes, they are similar because they have the same angle measures.

Front

What is the relationship between the sides of similar triangles?

Back

The lengths of corresponding sides of similar triangles are in proportion.

Front

If triangle A has sides of 3, 4, and 5, and triangle B has sides of 6, 8, and 10, are they similar?

Back

Yes, they are similar because the sides are in proportion (3:6, 4:8, 5:10).

Front

What does it mean for angles to be congruent?

Back

Congruent angles are angles that have the same measure.
