This document defines and provides examples of different types of angles including acute, right, obtuse, supplementary, complementary, bisected, vertical, linear pairs, and opposite rays. Acute angles measure less than 90 degrees. Right angles measure exactly 90 degrees. Obtuse angles measure more than 90 degrees. Supplementary angles add up to 180 degrees. Complementary angles add up to 90 degrees. Examples of different angles are provided from buildings, bridges, and other structures in New York City.
1. Angles In Life Project New York City By: MashaalZahid and Montana Gill
2. Acute Angles Acute angles measure less than 90 degrees. This Building has a angle on top, it is smaller then 90 degrees there fore making it an acute angle
3. Right Angles At the base of each arch way a Right angle is formed. A right angle is also called a 90 degree angle.
4. Obtuse Angles The bridge above this walk way in central park forms an obtuse angle
5. Supplementary Angles The Building side is an 180 degree surface. The flag cuts the building into two angles. The two angles add to 180 degrees.
6. Complementary Angles The stairs are bisecting the ninety degree angle. By bisecting the angle it is creating two complementary angle. The stairs are bisecting the ninty degree angle an. By bisecting the angle it is creeating two complementary angle.
7. Bisect Angle The Tip of the Empire state building is an example of a bisected angle because the building has a 180 degree angle but the tip, or needle part, bisects it. That makes it two ninety degree angles
8. Vertical Angles In this bridge a log of “X’s” are formed . Any time X’s are formed, a vertical angle is formed
9. Linear Pairs The Road that the arrow is pointing to is making a linear pair. The angles on either side of the line are adjacent and are supplementary.
10. Opposite Rays The Brooklyn bridge is an example of opposite rays because the pole holding up the bridge bisects the angle of the road. The road goes in both directions in a ray, heading opposite directions
