Monday, 10/12/98 Topic: Two More Concurrence Theorems.Reading GTC (Geometry Through the Circle), Chapter 4. This is applied to an introduction to moreĪn important application is the construction of the tangent lines to a given circle This uses someĭetailed geometry of the right triangle, especially the fact that the midpoint Of the vertex of right angles ABC for fixed A and B is a circle. Topic: Carpenter's Construction This lab will work through GTC Chapter 4. Reading GTC (Geometry Through the Circle),Chapter 3.

Math 487 Lab #1 Wednesday 9/28/98 Introduction to Geometer's Sketchpad Students will be introduced to the Sketchpad software by workingĬhapter 2 of GTC will also be used, so bringĮmail List Everyone should be on the email list.Results, including the Pythagorean Theorem. Wednesday 9/30/98 Topic: Similar Triangles and Pythagorean Theorem Criteria for similarity of triangles will be used to prove several.Monday, 9/28/98 Topic: Congruent Triangles SAS, SSS and ASA criteria for triangle congruence.So, we have proven that #M# is a modpoint of #AB# and #PM_|_AB#.Math 444 Syllabus and Topic Outline Math 444 Syllabus and Topic Outline #=>/_AMP=/_BMP# as angles of congruent triangles lying across congruent sides #AP# and #BP# #=> AM=BM# as sides of congruent triangles lying across congruent angles #/_APM=/_BPM# #=> Delta APM = Delta BPM# by side-angle-side theorem #=>/_APQ=/_BPQ# as angles of congruent triangles lying across congruent sides #AQ# and #BQ# #Delta APQ = Delta BPQ# - by side-side-side theorem #AP=BP=AQ=BQ# - each is a radius, which we have chosen What's more interesting is to prove that this construction delivers the perpendicular bisector.Īssume that #M# is an intersection of #AB# and #PQ#. The simple method is to choose it to be equal to the length of #AB#. For this the radius can be any, as long as it's greater than half of the length of #AB#. The only condition is for these circles is the existence two points of intersection, #P# and #Q#. Here the centers of these circles are the endpoints of a given segment #AB# and their radiuses must be the same. The easy way to construct a perpendicular bisector #PQ# to segment #AB# is pictured below. To construct perpendicular bisectors of a triangle #Delta ABC# you have to consider each side separately as a segment ( #AB#, #BC# and #AC#) and construct a perpendicular bisector to each of them.
