Question

which angles are supplementary to each other? ∠6 and ∠10 ∠4 and ∠3 ∠4 and ∠5 ∠5 and ∠12

Explanation:

Step1: Recall supplementary - angle definition

Two angles are supplementary if their sum is 180 degrees. Adjacent angles that form a straight - line are supplementary.

Step2: Analyze each option

• For ∠6 and ∠10: They are not adjacent and do not form a straight - line.
• For ∠4 and ∠3: They are adjacent and form a straight - line, so ∠4+∠3 = 180 degrees.
• For ∠4 and ∠5: They are not adjacent and do not form a straight - line.
• For ∠5 and ∠12: They are not adjacent and do not form a straight - line.

Answer:

∠4 and ∠3
