The measure of an angle is \( 132^{\circ} \). What is the measure of its supplementary angle?

To find the measure of the supplementary angle, you simply subtract the given angle from \( 180^{\circ} \). So, \( 180^{\circ} - 132^{\circ} = 48^{\circ} \). Therefore, the supplementary angle measures \( 48^{\circ} \). Did you know that the concept of supplementary angles dates back to ancient civilizations? The Greeks were particularly interested in geometry and used angles in their architectural designs, making sure to include considerations for both supplementary and complementary angles in their work! You can put this knowledge to practical use by applying it in real-world situations like interior design or architecture! Understanding how angles work helps create harmonious and aesthetically pleasing spaces, whether designing a room or constructing a building, ensuring the angles fit perfectly together for the desired effect.
