Question

2. Reflect XYZ about the line y=1 making RQL.

List all congruent sides and angles:

Answer 1

∠RQL≅∠XYZ

∠QRL≅∠YXZ

∠RLQ≅∠XZY

RQ≅XY, RL≅XZ, QL≅YZ

Explanation:

First we draw the line y=1 (parallel to x-axis and going throu y=1)

To reflect point Y over the line y=1 we draw a line from that point perpendicular to the line of reflecting (y=1), measure the distance from the point Y to the line y=1, and then measure the same distance on the other side of the line y=1 to get reflected point. Mark it. The angle at the reflected point will be congruent to ∠Y

The same goes for points X and Z

Angles at given and reflected point are congruent.

Sides of triangle are congruent if they lay between two congruent angles.
