Two points on the same plane are… _____________________. COPLANAR – on the same plane!. A. B. Finish the sentence : A line segment is different from a line because…. It has 2 endpoints, wheras a line goes on forever in both directions (has arrows on either end). (4,10). (-5, 2).

Finish the sentence:A line segment is different from a line because…
It has 2 endpoints, wheras a line goes on forever in both directions (has arrows on either end)
(4,10) (-5, 2) Find the coordinates for the midpoint between
(4,10) (-5, 2) (-.5, 6) or (-½, 6)
This is a special name for a point where two lines or rays intersect to form an angle.
Name complementary angles 2 1 3 6 4 5
Angles 2 and 3AND6 and 5 2 1 3 6 4 5
If . Solve for x 2 1 3 6 4 5
Study the figure: Given and solve for x j g h k w p f
Identify the acute angles in the figure below 2 1 6 3 4 5
An angle divides a plane into three distinct sections. Name them and draw an example.
Interior, exterior, on the angle a is on the angle Q (interior) a h b D (Exterior)
Given angle 2 is 49°, what is the measure of angle 5. What is the relationship between the two? 2 1 3 6 4 5
Angle 5 measures49° They are congruent because they are vertical angles.
Name two pairs of supplementary angles and how you know they are supplementary j g h k w p f
Answers will vary… they are supplementary because they add up to 180° (their rays make up the same line) j g h k w p f
Name the plane in two different ways… and state the rule z k h d b p M
Answers will vary… you name three non-collinear points (or the capital script letter) z k h d b p M
Name two supplementary angles. USE THEIR ANGLE NAMES and state the rule for how to name angles. j g k p f
<gkp and <pkf, <gkp and <gkj, <jkf and <gkj, <jkf and <fkpWe name angles using three points on the angle, the vertex always in the middle of the angle name. j g k p f
Name one ray and one line properly. h g a q
h g a q
Isan angle? Why or why not? j g h k w p f
NO!!!!!!!! NOOOO NOOOOO NOOOOOOOO NO!!!! THE VERTEX OF THE ANGLE MUST BE IN THE MIDDLE OF THE ANGLE NAME. j g h k w p f
Wowwww!! Right on! ;) … you see what I did there?
Which two angles are congruent? 1 3 4 2
1 and 4! 1 They have the same markings!!! 4
