Ask A Question


I can answer whatever questions you ask except how to trisect an angle. The ones I can answer include constructing parallel lines, dividing a line into n sections, bisecting an angle, splitting an angle in half, and almost anything else that is done in geometry.

Experience in the area

I have been assisting people in Geometry since the 80's.


I have an MS at Oregon State and a BS at Oregon State, both with honors.

Awards and Honors

I was the outstanding student in high school in the area of geometry and math in general.

Past/Present Clients

Over 8,500 people, mostly in math, with almost 450 in geometry.

What do you like about this subject?

It is an area of mathematics that I sometimes think is acute area to work with. My knowledge of it is quite obtuse. I bisect the questions down until I can answer each piece. Sometimes I go and use the complement to the question to get them right.

What do you still hope to achieve/learn in this field?

I hope to offer assistance to several people, including you ... that's why you're reading this, correct? I won't say I always give the "right" answer, for that just describes an angle, but most are "correct".

Something interesting about this subject that others may not know:

There are the same number of π radians in a circle as there are eggs most have for breakfast: 2. π almost looks like a profile of a pie ... you know, two sides and a top that overlaps the edges.

Something controversial or provocative about this subject

Many people have said geometry, but who have you heard say, "Gee, I'm a tree" ... We may think about the circle found in a trunk and measure the angles, but the relation stops there.

As stated, we have a semicircle at either end.  As also mentioned, these combine to form a circle.    What's left in between these two semicircles is a rectangle.  It can be seen that the width 3.5+3.5=7

2015-06-15 Angles:

I know of no calculator to do this, but what I can say is that the size of angles in a triangle add to 180.  This means if you know angle A and B, angle is found as 180 - A - B.    If we have a right

2015-02-04 geometry:

Note that a 30-60-90 triangle is half of a triangle with equal angles and sides.  This makes the hypotenuse one of the sides of the triangle with the shorter leg as one of the sides.  Since that leg is

2014-12-04 Circular Measure:

1. It is known that the area of a sector of a circle is πr.  It is also known that there are 2π radians in a circle.  If the measure of the angle is x radians, the area is xr/2.    Using this

2014-12-02 Arithmetic Progression:

A geometric series as the division of any two successive terms equal.  This means that (x+6)/(x+1) = 5x/(x+6).  This is the same as (x+6)(x+6) = 5x(x+1).  That gives x^2 + 12x + 36 = 5x^2 + 5x.  Subtracting
