week 6; angles
| Types of angles In geometry, angles can be classified according to the size of the angle.In these lessons, we will learn the following types of angles: right angles, acute angles, obtuse angles, straight angles, reflex angles and full angles. The following table shows the different types of angles: right angles, acute angles, obtuse angles, straight angles, reflex angles and full angles. Scroll down the page if you need more explanations about each type of angles, videos and worksheets.   What are the types of angles?The following video will demonstrate and distinguish between the different types of angles: right, acute, obtuse, straight, reflex and full angles.

Two lines or line segments that meet at a right angle are said to be perpendicular.
What are Acute Angles?An acute angle is an angle measuring between 0 and 90 degrees. What are Obtuse Angles?An obtuse angle is an angle measuring between 90 and 180 degrees. What are Straight Angles?A straight angle is a straight line and it measures 180 degrees.
What are Reflex Angles?A reflex angle is an angle measuring between 180 and 360 degrees. What are Full Angles?A full angle is an angle of one complete turn which is 360 degrees. |
