Question 1. Prove that if two lines intersect each other, then the bisectors of vertically opposite angles are in the same line. Solution: Let AB and CD be two intersecting lines intersecting each other in O. OP and OQ are bisectors of ∠AOD and ∠BOC. ∴ ∠1 = ∠2 and ∠3 = ∠4 …(i) Now, ∠AOC = ∠BOD [vertically … Se mer Question 1. If an angle is half of its complementary angle, then find its degree measure. Solution: Let the required angle be x ∴ Its complement = 90° – x Now, according to given … Se mer Question 1. In the given figure, AB CD, ∠FAE = 90°, ∠AFE = 40°, find ∠ECD. Solution: In AFAE, ext. ∠FEB = ∠A + F = 90° + 40° = 130° Since AB CD ∴ ∠ECD = FEB = 130° Hence, … Se mer Question 1.
