Similar figures

The pair of figures is similar. Find the missing side.

• x = 9
• x = 28
• x = 7
• x = 63

Solve for X.

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

• Yes, similar because they are the same shape and side lengths are proportional.
• No, not similar because they are the same shape, but side lengths are not proportional.
• Yes, same shape
• No, different sizes

Are these triangles similar?

• Yes
• No

Matching sides are called

• Corresponding Sides
• Corresponding Angles
• The Same
• Congruent Sides

All angles in similar figures are congruent.  

• True
• False

Are the following similar? Why or why not?

• Yes
• No, the corresponding angles are not equal.
• No, the ratios of the corresponding sides are not equal.
