2. 1.1 – 1.3 Key Ideas Review Wednesday, October 5

3. Objective • Students will be able to identify the key ideas from sections 1.1 – 1.3

4. Directions • Work with seat partner to complete the Key Ideas worksheet • CAN USE NOTES • Should be working on task at a quiet conversation level • You should only be talking to your partner • No cross group conversations • If you need help, raise your hand to ask Ms. Pittman • You should NOT ask another partner group • Stay in your assigned seats • Participation looks like: on task conversation with partner, writing answers on worksheet • Non-participation: looking out of the window, talking with non-partner, out of seat, etc.

5. 5 minutes: 1.1 Key Ideas • What does it mean to be an undefined terms? • What are the three undefined terms in geometry? • Naming points, lines, and planes. • There is/are way(s) to name a point, which is/are . • There is/are way(s) to name a line, which is/are . • There is/are way(s) to name a plane, which is/are . • Two points are collinear if • Three points are coplanar if

6. 1.2 Key Ideas AnswersCorrect in a different colored pen • What does it mean to be an undefined term? Cannot be defined; can only be described using examples and descriptors • What are the three undefined terms in geometry? Points, lines, planes • Naming points, lines, and planes. • There is/are 1 way(s) to name a point, which is/are capitol letter. • There is/are 2 way(s) to name a line, which is/are line + lowercase cursive letter or 2 collinear points with a line with arrows above it. • There is/are 2 way(s) to name a plane, which is/are plane + capitol cursive letter. • Two points are collinear if They are on the same line • Three points are coplanar if They are on the same plane, but are not collinear

7. 8 minutes: 1.2 Key Ideas • What are two ways in which a line segment differs than a line? • Segment addition • If given the measure of the parts of a segment, how do you find the measure of the whole segment? • If given the measure of 1 part of a segment and the whole segment, how do you find the measure of the other part of the segment? • If the segment is split into congruent parts and given the measure of the whole line segment, how do you fine the measure of the parts of the segment?

8. 1.2 Key Ideas Answers Correct in a different colored pen • What are two ways in which a line segment differs than a line? A line segment has endpoints and is measurable. • Segment addition • If given the measure of the parts of a segment, how do you find the measure of the whole segment? Add the measures of the parts to find the measure of the whole • If given the measure of 1 part of a segment and the whole segment, how do you find the measure of the other part of the segment? Subtract the measure of the part from the measure of the whole to find the measure of the other part • If the segment is split into congruent parts and given the measure of the whole line segment, how do you find the measure of the parts of the segment? Divide the measure of the whole by the number of congruent segments to find the measure of one part?

9. 8 minutes 1.3 Key Ideas • What is the general distance formula given two points a and b on a number line? • What is the general formula for the distance between two points (x1, y1) and (x2, y2)? • What is the formula for the distance between two points using the Pythagorean Theorem? • What is the general midpoint formula given two points a and b on a number line? • What is the general midpoint formula given two points (x1, y1) and (x2, y2)?

10. 1.3 Key Ideas Answers Correct in a different colored pen • What is the general distance formula given two points a and b on a number line? |a – b| = d or |b – a| = d • What is the general formula for the distance between two points (x1, y1) and (x2, y2)? d = sqrt[(x2 – x1)2 + (y2 – y1)2] • What is the formula for the distance between two points using the Pythagorean Theorem? a2 + b2 = c2 [a represents the distance between the x values and b represents the distance between the y values] • What is the general midpoint formula given two points a and b on a number line? (a + b)/2 • What is the general midpoint formula given two points (x1, y1) and (x2, y2)? ( (x1 + x2)/2 , (y1 + y2)/2 )

11. Exit Slip • Distance between two points is always • one number • one number, always positive • one number, always negative • an ordered pair • Midpoint between two points on a coordinate plane is always • one number • an ordered pair • an ordered pair, always positive • an ordered pair, always negative
