Complementary angles, which are two angles that add up to 90 degrees, can be observed in various architectural designs and elements. Here are some real-world examples:

1. **Roof Design**: Many buildings feature pitched roofs with two sections that meet at a ridge. The angles formed by the slopes of these sections are often complementary. For instance, a roof might have one slope at a 30-degree angle and the other at a 60-degree angle.

2. **Staircases**: In the design of staircases, the angle of the staircase relative to the level floor and the angle of the risers can be complementary angles. For example, if the staircase rises at a 37-degree angle, the angle with the horizontal can be 53 degrees, making them complementary.

3. **Windows**: Certain window designs, especially those in modern architecture, may incorporate angles that combine to form complementary angles. For example, if a window is set at a 45-degree angle to the wall, the angle it makes with the floor can be 45 degrees as well, resulting in complementary angles.

4. **Furniture and Space Planning**: In interior architecture, the layout of furniture and fixtures may utilize complementary angles to create visually appealing arrangements. Pieces that are placed at angles that complement each other can help maximize space and enhance aesthetics.

5. **Non-Right Angle Corners**: Some buildings, especially those with modern or unconventional designs, feature corners that form complementary angles rather than traditional right angles. For example, a corner of a room might have one angle of 70 degrees and the other angle of 20 degrees.

6. **Facade Features**: Certain facades, particularly in contemporary architecture, may utilize sloped surfaces or angled protrusions that create complementary angles with adjoining surfaces.

7. **Bridges**: In structural engineering, particularly for bridges, the angles formed between the decks and the supports can be designed to be complementary, optimizing both aesthetics and strength.

These examples demonstrate how complementary angles are used in various aspects of architecture, contributing to both functionality and design aesthetics.
