2. Fundamental Questions 1.What does distance between a point & a line really mean? a.This becomes our definition for distance between a point and a line 2.How do we measure the distance between 2 || lines?

3. Fundamental Questions 3. What does equidistant mean? Same distance apart at every point. A point is said to be equidistant from a set of objects if the distances between that point and each object in the set are equal. http://en.wikipedia.org/wiki/Equidistant 4.

5. 11/1/2011 Obj: SWBAT find the distance between a point and a line and the distance between parallel lines by applying knowledge of slopes and the distance formula. Bell Ringer: Finish example from yesterday HW: pg 163 #19, 21, p. 181 #14, 16 & #22-38 evens, 39; Read Section 4.2. Take Notes copy proof of angle sum theorem Quiz 4.1, 4.2 Friday. pg 155 #34-37 Fundamental Questions 1.What does distance between a point & a line really mean? 2.How do we measure the distance between 2 || lines? How do we classify triangles by angles and sides?.

9. FQ 2: What is it about 3 rd angles in a triangle? Third Angle Theorem Theorem 4.2 Third Angle Theorem – If 2 angles of one triangle are congruent to 2 angles of a 2 nd triangle, then the third angles of the triangles are congruent. FQ 3: Right angles have properties too, what are they? Corollaries 4.1, 4.2

10. Exterior Angle Theorem Theorem 4.3 Exterior Angle Theorem – The measure of an exterior angle of a triangle is equal to the sum of the measures of the two remote interior angles. (Pg 109) FQ 4: What is an exterior angle and how do we find it? FQ 5: What is a remote angle? FQ 6: Why does the exterior angle theorem work any way?
