Transcribed Image Text:The image shows a diagram of intersecting lines with angle measurements. Here's a detailed description:
- There are two horizontal lines: one at the top labeled "f" and one below it labeled "e."
- Two diagonal lines intersect these horizontal lines, forming several angles.
- The left diagonal line is extended and intersects the horizontal lines, labeled "d" and "c."
- The right diagonal line intersects at angles labeled "b" and "a."
- The angle "b" measures 140 degrees, and angle "a" measures 80 degrees.
- The point of intersection creates vertical angles, with angle "e" corresponding to angle "b" and angle "f" corresponding to angle "a."
These intersecting lines and angles can be used to study properties such as vertical angles being congruent and the angle sum property of intersecting lines.
