Calculate the distance point A is from the origin on the y-axis.
A (7,-8)
a. 7 units
b. 8 units
c. 15 units
d. 1 units

In the figure below, ∠dec ≅ ∠dce, ∠b ≅ ∠f, and segment df is congruent to segment bd. point c is the point of intersection between segment ag and segment bd, while point e is the point of intersection between segment ag and segment df. the figure shows a polygon comprised of three triangles, abc, dec, and gfe. prove δabc ≅ δgfe.
