Problem 500. Circle, Diameter, Chord, Perpendicular, Measure.
Level: High School, College, SAT Prep.
The drawing shows a circle of diameter AB. The chords AC and BD
meet at E. EF is perpendicular to AB. FC and BD meet at G. If DE
= 5 and EG =3, find the measure of BG.
Geometry problem solving
Geometry problem solving is one of the most
challenging skills for students to learn. When a
problem requires auxiliary construction, the
difficulty of the problem increases drastically,
perhaps because deciding which construction to
make is an illstructured problem. By
“construction,” we mean adding geometric figures
(points, lines, planes) to a problem figure that
wasn’t mentioned as "given."
How to Solve It, Interactive Mind Map
George Pólya's 1945 book "How to Solve It, A new
aspect of Mathematical Method", is a book
describing methods of problem solving. It
suggests the following steps when solving a
mathematical problem: (1) First, you have to
understand the problem. (2) After understanding,
then make a plan. (3) Carry out the plan. (4)
