👉 A vertex or zenith.
Alright class, settle down and listen close to me, We’re tackling words today, for all the world to see! You’ve got the dictionary, a helpful guide you see, Pointing out “vertex” and “zenith,” quite cleverly. But what does "vertical" really mean, you ask with glee? Let's break it down, so clear for you and me! Vertical means straight up, or straight down, you agree? Like a building tall, reaching high for the free! Think of a flagpole, standing proud and bright, Or a mountain rising, bathed in morning light. "Vertex" is where lines meet, a point so neat, And “zenith” is the highest point, bittersweet! But "vertical," my dears, describes a line’s decree – It's up or down , perfectly straight and free! Do you understand now? Raise your hand if you do! Let’s move on to our next word, shiny and new!
