Final answer:
Vertically opposite angles occur when two lines intersect, with examples such as the corners of a window, street intersections, scissor blades, criss-cross chair or table legs, and a book opened at the spine.
Step-by-step explanation:
Vertically opposite angles occur when two lines intersect. At this intersection, pairs of equal but opposite angles are formed facing vertically to each other. Here are five examples from your surroundings:
- The four corners of a window: These are formed by two intersecting lines, the line along the height, and the line on the width of the window.
- Street intersections: Whereever two roads meet at right angles, you have vertical angles.
- Scissors: The two blades form vertically opposite angles when opened or closed.
- Criss-cross chair legs or table legs: They form vertically opposite angles where they intersect.
- A book opened at a right angle: The two pages in view form vertically opposite angles at the center where they meet.
