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 »

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 »

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 »

Examples of vertical angles in real life settings include the black and white railroad crossing signs found on roadways near railroads, open scissors and the letter "X." Other examples include the point where ceiling bea... More »

An acute angle is any angle with a measure of less than 90 degrees. Obtuse angles measure more than 90 degrees, and right angles measure exactly 90 degrees. More »

Obtuse angles are seen on most house rooftops, as the two roof surfaces slope down from it. Other real world examples of an obtuse angle include the angle between the screen and the base of an opened laptop, a hockey sti... More »

A kite is a real life example of a rhombus shape. However, while a kite has a rhombus shape, it is not a rhombus. More »
