Question

transformations (8.g.a.2). 4. for each pair of shapes, decide whether or not shape a is congruent to shape b. explain your reasoning. a. first pair

Explanation:

side - lengths
Count the grid - unit lengths of corresponding sides of Shape A and Shape B. If all corresponding sides are equal in length.

Step2: Check angles

Observe the angles of corresponding vertices of Shape A and Shape B. If all corresponding angles are equal.
In this case, by counting the grid - unit lengths of the sides of the two shapes and observing the angles, we can see that Shape A can be translated and rotated to exactly overlap with Shape B. All corresponding sides and angles are equal.

Answer:

Shape A is congruent to Shape B because all corresponding sides and angles are equal, and Shape A can be transformed (translated and rotated) to coincide with Shape B.
