Vertical Angles

Vertical angles are a set of lines that cross each other to create two congruent angles. The image above shows a pair of skis. Skis can be found at a sport shop or winter store. Any person who lives somewhere in the mountains normally has a pair of skis, or people who are going on vacation to go skiing. When the skis are crossed like this it creates a vertical angle. As it shows in the picture, the measure of angle A is equal to the measure of angle B.

Angle Bisector

This is a leaf that can be found on trees outside. The veins on the leaf represent lines. The two lines that connect in the middle and are drawn in black create an angle. The line that comes between the angle is the angle bisector. Leafs can be used in the real world for art projects, they get raked up in the fall, and some can be eaten. Regular people can see and use leaves everyday. Scientist can study them. Leaves are parts of plants which are studied in the biotechnology industry.This image is from the internet.https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgiiS3QVDuLgTHU4xBWGfvccH15MKEjSz5yHQzrCMTdiCmeoBonrw-1gxUwO9HKIq9CdCKePYOGDYGX4GXyry8Tjl0oqUKsziljO18Oj7cP4RzZftH5BD3EMeSgHhDw4_EuR2Aur0L7F7M/s1600/LEAF+VEIN.JPG

Congruent Angle

This image is of a pumpkin pie that is being cut up into even pieces. Pies can be found at a local grocery store. This item is made from the food industry. When a pie is cut evenly it is a lot like congruent angles. Congruent angles are when two angles have the same measure. Because each piece of pie should be the same size they act like congruent angles. This is an example of how geometry can be used in the outside world. Many people around the world buy pies and cut them into pieced everyday. Now readers know that when they are trying to make even pieces they are actually using congruent angles.
