Question

Geometry - Should be pretty easy

Answer 1

DQR

Explanation:

DEF is complentary to DQR

Answer 2

∆DQR

Explanation:

You want the similarity statement if the triangles shown are similar.

Similarity

Triangles will be similar if they have congruent corresponding angles, or proportional corresponding sides.

No angles are shown in the figure, but side lengths are given.

We expect that if the triangles are similar that the corresponding sides will be ...

• DE ⇔ DQ
• EF ⇔ QR
• FD ⇔ RD

Proportion

The attached calculator display shows the ratios of these side lengths are the same: 14/3. That means ...

∆DEF ~ ∆DQR
