Question
Title: Reflection of Triangle \( \triangle ABC \) Across Line \( \ell \) **Objective:** To plot the image of triangle \( \triangle ABC \) under a reflection across line \( \ell \). **Instructions:** 1. **Initial Setup:** - Observe the graph provided above. It displays two coordinate planes overlaid with grids. - The triangle \( \triangle ABC \) is presented in the upper coordinate plane. The vertices of the triangle are labeled as \( A \), \( B \), and \( C \). 2. **Reflection Line \( \ell \):** - The line \( \ell \) acts as the reflection axis and is represented by a horizontal black line running across the middle of the graph. - This line splits the graph into two equal parts: an upper plane and a lower plane. 3. **Step-by-Step Reflection Process:** - Each vertex of \( \triangle ABC \) must be "flipped" over the line \( \ell \). The new positions of these vertices will form the reflected triangle in the lower coordinate plane. 4. **Resulting Reflected Triangle:** - As shown in the lower plane of the graph, the reflected image of \( \triangle ABC \) appears. Its vertices should be at the same perpendicular distance from \( \ell \) as those of the original triangle, but on the opposite side of \( \ell \). 5. **Analysis of Reflected Triangle:** - The reflected triangle is congruent to the original triangle \( \triangle ABC \). - Each corresponding side and angle are equal, maintaining the properties of geometric reflections. **Diagram Explanation:** - The upper part of the image shows the original triangle \( \triangle ABC \) in blue. - The horizontal line \( \ell \) acts as the line of reflection. - The lower part displays the reflected triangle in green, demonstrating the outcome of the reflection process. Use this graph to understand the geometric properties of reflections and to practice plotting reflected images on coordinate planes.
