Question

which angles are supplementary to each other? ∠3 and ∠7 ∠9 and ∠10 ∠7 and ∠4 ∠2 and ∠6

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 ∠3 and ∠7: They are corresponding angles, not supplementary.
• For ∠9 and ∠10: They are adjacent angles and form a straight - line. So, ∠9+∠10 = 180 degrees.
• For ∠7 and ∠4: They are not related in a way that their sum is 180 degrees.
• For ∠2 and ∠6: They are not supplementary.

Answer:

∠9 and ∠10
