Given the information marked on the diagrams below,
which pair of triangles can not always be proven congruent.

Skye says that the two triangles below are
congruent. Margaret says that the two triangles are
similar. Are Skye and Margaret both correct? Explain why.

Two triangles are similar, and the ratio of each pair
of corresponding sides is 2:1. Which statement
regarding the two triangles is not true?

The accompanying diagram shows two similar
triangles.

Which proportion could be used to solve for x?

The Rivera family bought a new tent for camping.
Their old tent had equal sides of 10 feet and a floor
width of 15 feet, as shown in the accompanying
diagram.

If the new tent is similar in shape to the old tent
and has equal sides of 16 feet, how wide is the
floor of the new tent?
