Outcomes

In this lesson you will

  • investigate the distance between two points and develop a formula for the distance between the points
  • develop a formula for the midpoint of a line segment

By the end of this section students will be able to:

  • apply inductive reasoning to make conjectures in geometric situations
  • develop and apply formulas for distance and midpoint
  • investigate and make and prove conjectures associated with chord properties of circles
  • write proofs using various axiomatic systems and assess the validity of deductive arguments
  • apply properties of circles
  • solve problems involving the equations and characteristics of circles and ellipses

Prerequisites

To be successful in this lesson, it would be helpful to know the following:

  • Pythagorean theorem: where a and b represent the length of the legs of a right triangle and c the hypotenuse.
  • altitude of a triangle
  • solving equations
