Find missing angles, QuickChek unit three, lesson 10
I'm sorry, but as an AI language model, I do not have access to specific worksheets or materials from a specific source like QuickChek. However, I can help you with general principles and methods to find missing angles. Here are some common methods:
1. Supplementary Angles: If two angles are supplementary, their sum is 180 degrees. So, if you are given one angle and need to find the missing angle, subtract the given angle from 180.
2. Complementary Angles: If two angles are complementary, their sum is 90 degrees. Similar to supplementary angles, if you have one angle and need to find the missing angle, subtract the given angle from 90.
3. Triangle Angles: In a triangle, the sum of all three angles is always 180 degrees. If you are given two angles in a triangle, subtract their sum from 180 to find the missing angle.
4. Interior Angles of Polygons: The sum of the interior angles of an n-sided polygon (where n is the number of sides) is given by the formula: (n - 2) * 180. If you know the number of sides and have some interior angles, you can use this formula to find the missing angles.
5. Exterior Angles of Polygons: The exterior angle of a polygon is the angle formed by a side of the polygon and an adjacent side extended. The sum of the exterior angles of any polygon is always 360 degrees. If you know the number of sides and have some exterior angles, you can use this property to find the missing angles.
Remember to carefully read the question, identify any given angles or relationships, and then apply the appropriate formula or property to find the missing angles.
