Question

look at ∠bdc and ∠adb in the image below. which of the following is the best description for this pair of angles? complementary acute supplementary right

Explanation:

Step1: Recall the definitions

• Complementary angles: Two angles whose sum is \(90^{\circ}\).
• Acute angles: Angles that measure less than \(90^{\circ}\).
• Supplementary angles: Two angles whose sum is \(180^{\circ}\).
• Right angles: Angles that measure \(90^{\circ}\).

Step2: Analyze the pair of angles \(\angle BDC\) and \(\angle ADB\)

From the image, we can see that \(\angle BDC+\angle ADB = 90^{\circ}\) (since they form a right - angle at \(D\)).

Answer:

complementary
