Identifying supplementary, complementary, and vertical angles

Identifying supplementary, complementary, and vertical angles
Description
Exercise Name:	Identifying supplementary, complementary, and vertical angles
Math Missions:	7th grade (U.S.) Math Mission
Types of Problems:	1

The Identifying supplementary, complementary, and vertical angles exercise is under the 7th grade (U.S.) Math Mission. This exercise practices telling whether two angles are supplementary, complementary, or vertical.

Types of Problems

There is one type of problem in this exercise:

1. What is the relationship between the two angles?: On this problem two angles angle are drawn and the user is asked to click the correct response.

   

   Find the relationship between the two angles.

Strategies

Basic knowledge of supplementary, complementary, and vertical angles are required for this exercise.

Vertical angles are angles opposite each other where two lines cross. Complementary angles are when two angles add up to $90^\circ$. A common case is when they form a right angle. Supplementary angles are when two angles add up to $180^{\circ}$. A common case is when they lie on the same side of a straight line.

Real-life Applications

1. Engineers and architects use angles for designs, roads, buildings and sporting facilities.
2. Athletes use angles to enhance their performance.
3. Carpenters use angles to make chairs, tables and sofas.
4. Artists use their knowledge of angles to sketch portraits and paintings.
