    Protractor is a 'D' like scale thing used to measure the angle..seen it anywhere??

    You can also draw a right triangle, measure the sides and the angle can be derived from sin-1(x/y)

    what do you know about right triangles? or triangles in general.... their angles all add up to what number?

    okay, let me tell u one thing, the sum of angles inside a triangle=180 degrees... and the angle 'j' is a 90 degree means a verical(right angle)

    so 90+65+F=180 and now u can find out the angle F which is nothing but 25degrees

    and angle E is 45+25+E=180 => 110 degrees

    ok, so is <1=65

    and u see that line DE is parallel to the ray passing through j, so diagonally opposite angles are same i.e. angle DJH=65degrees

    no no angle1=F=25degree

    Ok, I will study your previous notes and hopefully understand angles. Thanks so much for your help. Geometry is new to me and i'm totally confused

    1=25deg 2=115 4=65 3=65 5=50 degrees

    The answer to this question really depends on what level of math you are trying to use as well as what information is given.

    Tell me why angle 4 does not equal angle 5 as they are vertical angles/

    I would double check believe Angle 4 = Angle 5 =50 degrees. Angle 1 = 25 dcegrees, angle 2 = 115 Degrees, angle 3 = 65 degrees.

    i guess the only way is to use a use a protractor:):) if not i have no clue at all.lol

    That would work if the angles were drawn accurately!

    @Radar: I've always had a problem with dooses myself. As to measuring angles, again, depends on your givens and your level of math. In the included diagram, all the givens were angles geometrical logic could be used.
