Vocabulary

Corresponding objects: Those that appear in the same place in two similar situations.

Similar: Figures that have the same shape, but not necessarily the same size.

Congruent: Figures that have the same shape and same size.

Concept

Identifying corresponding angles and sides of polygons. 

Rules

If two polygons are similar, then their corresponding angles are congruent and the measures of their corresponding sides are proportional.

Use the angle markers to match the corresponding angles and sides.

Example

Drag the correct answer choice to match the corresponding angles.

Solution

When matching up corresponding angles and sides, we can use the angle markers to guide us. Angle A has a single congruent marker, as does E. Therefore, angle A and E are congruent and corresponding angles. Similar arguments can be made for angles B and F, angles C and G, and angles D and H.
