Question 62
Using the given information, name the right angles in each part of the given figure.
a) BA⊥BD
b) RT⊥ST
c) AC⊥BD
d) RT⊥SW
e) AC⊥BD
f) AE⊥CE
g) AC⊥CD
h) OP⊥AB
A right angle is an angle of measure 90∘. It is formed by two perpendicular lines.
a) ∠ ABD because BA⊥BD.
b) ∠ RTS because RT⊥ST.
c) ∠ ACD and ∠ ACB because AC⊥BD.
d) ∠ RTW and ∠ RTS because RT⊥SW.
e) ∠ AED, ∠ AEB, ∠ BEC and ∠ DEC because AC⊥BD and E is their point of intersection.
f) ∠ AEC because AE⊥CE.
g) ∠ ACD because AC⊥CD.
h) ∠ AKO, ∠ AKP, ∠ BKO and ∠ BKP because OP⊥AB and K is their point of intersection.
