My Acrostic (tangent)



Tangent is a straight line that touches a circle but does not cut it.
Any tangent line to a circle is perpendicular to the radius drawn to the point of tangency.
Not only a line but it is also a trig function.
GA (line) is a tangent. Therefore, the angle between tangent GA and chord BC (angle1) is congruent to the inscribed angle subtended by the opposite side of the chord(angle 2).
EG (line) and GB(line) are congruent because they are drawn from the same point.
Note that in the case of a circle, the tangent line will touch it ONLY at a single point.
Tangent and radius create a 90 degree angle when they intersect.

What a great idea, combining a diagram with your acrostic! Very clever!

A couple of points to clear up to get your mark:

EG and GA are not necessarily congruent, look at the "Tangent Theorem" again. ;-)

The second N (tangeNt) is the same point as the first T (Tangent).

The last T (tangenT) is the same as A (tAngent).

You can't use the same concept twice.

You've almost got your mark -- you can do it!
