With respect to the previous problem, which of the following angles is NOT equal to x (∠ABC)?
Considering AB as the transversal for the parallel lines ⟷AD and ⟷BC
x = a [corresponding angles]
a = z [vertically opposite angles]
x = y [vertically opposite angles]
b = 180∘−x
Which of the following angles is NOT equal to x (∠ABC)? [PR and QS are parallel lines AD and BC are parallel lines]
With respect to the previous problem of construction of a 30∘ angle, what angle would you get at the end of two arcs drawn in the following fashion?
With P as centre and any radius, draw an arc as shown, which cuts in A. This is the first arc. With A as centre and the same radius, cut this arc in B. This is the second arc.
