A ramp forms an acute angle in relation to the ground, and a ladder forms an acute angle when leaned against a building. The sharply angled, pointed shape of a slice of pizza is another common example. One famous acute a... More » Math Geometry

A typical trigonometry problem is: If the bottom of a ladder leaning against a building is 15 feet from the base of the building and forms a 45-degree angle with the ground, how tall is the ladder? Another example involv... More » Math Geometry Trigonometry

A ladder placed against a building is a real life example of a linear pair. Two angles are considered a linear pair if each of the angles are adjacent to one another and these two unshared rays form a line. The ladder wo... More » Science Earth Science
