Geometry (Class 4)

Overview
In today’s class we pick up where we left last time-- finding the areas of the shapes. We then continue our work building our understanding of the Pythagorean theorem and using our algebra skills to prove that it is always true. Finally we will see how the Pythagorean theorem can be used to find the distance between any two points on a coordinate plane when the coordinates for the points is known.

§1.3 (Txt. p. 17) Segments and Their Measures

Vocabulary
constraint
coordinate
distance
segment addition postulate
distance formula
congruent segments

Key Attitudes
Math is about investigating and dicovering.

Key Ideas
Finding the distance between two points on a number line and in the coordinate plane.

Key Skills
