Manhattan Geometry : Lines & Angles Q)14

by xerocoool Sat Sep 13, 2014 12:48 pm

Hi Tommy,

Q14) Problem Set Questions - Lines & Angles

I understood the explanation given in the book. But I have an additional doubt.

Need to prove : a+k :: given: g = 90

Is the following approach right ? (does not give the right answer)

g = 90
f = 90 (vertically opposite to angle g)
b = 90 (corresponding angle to f)
a+b = 180 (angles on a st. line)
a= 90
d = 90 (angles on a st. line)

Now,

is it right to assume angle "d" = angle "k" ? (as corresponding angles)

so k becomes 90

a + k = 180

Thanks

Hey Xero,

I don't see why b would correspond to f, nor what d has to do with k. You can only connect up angles if they are on the same line, part of the same polygon, or if given relevant lines are parallel or perpendicular. The only two lines we have here that are perpendicular don't help make the connections you mentioned.
