practice solving problems involving complementary and supplementary angles.\nwhich angle pairs are supplementary? check all that apply.\n□ ∠1 and ∠2\n□ ∠4 and ∠3\n□ ∠4 and ∠5\n□ ∠7 and ∠5\n□ ∠3 and ∠6
Answer
Explanation:
Step1: Define supplementary angles
Supplementary angles sum to $180^\circ$ (form a straight line).
Step2: Check ∠1 and ∠2
These are adjacent but do not form a straight line; sum ≠ $180^\circ$.
Step3: Check ∠4 and ∠3
These form a straight line; sum = $180^\circ$.
Step4: Check ∠4 and ∠5
These form a straight line; sum = $180^\circ$.
Step5: Check ∠7 and ∠5
These are same-side interior angles of a triangle; sum ≠ $180^\circ$.
Step6: Check ∠3 and ∠6
These form a straight line; sum = $180^\circ$.
Answer:
∠4 and ∠3, ∠4 and ∠5, ∠3 and ∠6
