Geometry/construction

1- given a unit line segment AB (2 cm) construct a segment of lenght (1+Sqrt[5])/2 2- given the unit segment abobe and construct a segment of lenght Sqrt[2/3]

Geometry/construction

- given a daimeter AB of a circle and a point P as shown in figure construct with straight edge alone a perpendicular from P to AB

Geometry/construction

- A farmer wishes to erect a striaght fence that will bisect the angle formed by two existing (straight) fences. unfortunetly the vertex of the angle is in the middle of a lake. how can we locate the fence line using straight edge and compass. see figure in attached file.

Create ways to teach surface area and volume to students

Creating ways to teach surface area and volume. I am especially interested in methods which will help students connect geometry to life in the real world.

Discussion question

Brainstorming crative ways to teach surface area and volume. the teachers are especially interested in methods which will help teh students connect geometry to life in the real world because student motivation has sometimes been lacking in this course.
