What is an effective way to reinforce the concept that complements balance each other?

Using paired physical objects is an effective way to reinforce the concept that complements balance each other because it provides a tangible, visual representation of the relationship between complementary angles. For instance, using two objects that can be positioned together to form a straight line can help students see that two angles are complements when their measures add up to 90 degrees. This hands-on approach engages students, making the concept more relatable and easier to understand.

In contrast, teaching complements as separate concepts may lead to confusion, as students might not grasp their interdependence. Focusing solely on numerical examples can also miss the opportunity for learners to connect with the material practically and visually. Ignoring this relationship in practical applications would overlook the importance of understanding how complementary angles function in real-world scenarios, ultimately hindering a student's mathematical comprehension.
