pls. help me
@jim_thompson5910 can you help me??
what kind of line is line m
i dont know too
look up all the geometry terms and definitions for circles in your textbook
our textbook doesn't have the definitions
check out this page http://www.sparknotes.com/math/geometry1/circles/section3.rhtml
@jim_thompson5910 is number 1 secant?
that is correct
This will help. http://properties-of-circles.blogspot.com/ Anyhow, I can only answer few. I'm not sure with some. m is a secant line n is a tangent line angle 1 is a central angle angle 2 is an inscribed angle /not that sure angle 3 is an angle formed by secant and tangent lines C is the center of the circle A is a point on the circle /not sure Segment AB is a diameter Segment BC is a radius Segment BD is a chord E is the intersection of tangent and secant lines /don't know if there's a term for that angle B is an angle in a semicircle (it is 90 degrees) D is point of tangency Segment AC is radius angle 4 is an inscribed angle /not that sure though
@jim_thompson5910 can you check my answers?? 1. secant 2.tangent 3.central angle 4.inscribed angle 5.angle formed by a secant and a tangent 6.central angle 7.tangent 8.diameter 9.radius 10.secant 11.point of tangency 12.inscribed angle 13.tangent 14.radius 15.inscribed angle
for #6, C is a point, not an angle
# 7 is incorrect
# 10 is incorrect
# 11 is incorrect
# 13 would be the point of tangency
@jim_thompson5910 this is my last question is 4 inscribed angle? is 7 point on the circle? is 11 intersection of tangent and secant lines? is 12 angle in a semicircle? is 15 inscribed angle?
is 4 inscribed angle? yes
for #7, that's all we can say really, so yes I guess you could also say that point A is one point of the intersection of the secant line and the circle
is 11 intersection of tangent and secant lines? yes
you already did 12 and your original answer is correct
same with #15, your original answer for that is correct
