- 1. ANGLES IN LIFE PROJECT Created By: Alex Windsor Topic: Nature Ms. Purdy Geometry D October 3, 2008
- 2. ACUTE ANGLES To the left is a picture of an acute angle. An acute angle is an angle that is less than 90 degrees, (or a right angle).
- 3. RIGHT ANGLES Thispicture is a picture of a right angle. A right angle is an angle that adds up to 90 degrees.
- 4. OBTUSE ANGLES Below is a picture of an obtuse angle. An obtuse angle is an angle that is larger than a right angle; where the lines extend out farther than if they were straight.
- 5. To the left is STRAIGHT ANGLES a straight angle, and that is when the right angle moves its lines downward to create two straight lines on either sides of the points.
- 6. COMPLEMENTARY ANGLES To the right is a picture of a complementary angle. A complementary angle is two angles whose measures both have a sum of 90 degrees. There are a couple ways in which you could create a complementary angle with these images on the right. http://davidwrunyan.blogspot.com/
- 7. SUPPLEMENTARY ANGLES Tothe right is a supplementary angle. This means that these two angles add up to 180 degrees.
- 8. BISECTED ANGLES Pictured above is a bisected angle. A bisect angle is an angle that divides something into two equal parts, so that its spilt halfway down the middle.
- 9. VERTICAL ANGLES To the right is a vertical angle. A vertical angle is an angle with two nonadjacent angles formed by 2 intersecting lines. Also, all vertical angles are congruent.
- 10. To the left is LINEAR ANGLES a linear angle. A linear pair is a pair of adjacent angles whose noncommon sides are opposite rays. The angles in a linear pair also have a measure that add up to 180 degrees.
