3 angle A number FORMED BY two NONCOLLINEAR RAYS through A usual ENDPOINT.
4 angle The 2 NONCOLLINEAR beam (ray BP & ray BC) are the sides of one angle.
5 angle The point where the rays crossing is called the crest of an angle.
6 angle MNEMONIC S- Sides are 2 non-collinear rays. E- Endpoint is also called vertex. R- Rays room the 2 sides. V- peak is the typical endpoint.
7 AN edge SEPARATES A aircraft INTO 3 PARTSINTERIOR ANGLE- allude D EXTERIOR angle – allude H THE edge ITSELF P, A, W,C ●H ●D
9 naming AN edge
10 USING 3 POINTS. EXAMPLE: ABC orCBA PBW or WBPAn angle is named by: utilizing 3 POINTS. EXAMPLE: ABC orCBA PBW or WBP
11 An angle is called by: 2. By THE crest ALONE. EXAMPLE: B
12 An edge is called by: 3. BY using A NUMERAL. EXAMPLE: 1 1 1
13 exercises 3 2 1
14 NAME THE ANGLES utilizing 3 POINTSNAME THE ANGLES using A character 3 2 1
15 WHAT room THE political parties OF edge 3.
You are watching: Formed by two noncollinear rays with a common endpoint
ANOTHER surname OF angle 1. B or ABW PBC or ABC Segment AC and also ray AP 3 2 1
16 WHAT IS THE common SIDE the 2 and 3?Segment AC 3 2 1
17 Name angle Name the three angles in the diagram. Example 5WXY, or YXW YXZ, or ZXY WXZ, or ZXW You have to not name any kind of of these angles X due to the fact that all three angles have X together their vertex.
18 Degrees: Measuring angles Angles room measured in units referred to as DEGREES and also classified follow to their measures.
19 Acute angle an angle measuring in between 0 and 90 degrees
20 Obtuse angle an angle measuring in between 90 and also 180 degrees
21 Right angle an angle measuring exactly 90 degrees.
22 Obtuse angles an angle measuring between 90 and also 180 degrees
23 Degrees: Measuring angle We measure up the size of an angle utilizing a device called the PROTRACTOR.
25 exactly how TO usage A PROTRACTOR
26 Place the center point of the protractor on the peak of the angle.
27 Line increase the note labeled 0 top top either scale with one side of the angle.

28 Read the range where it drops on the other side that the angle.
29 Use a protractor because that exercises 1-2Construct one angle v a measure of 45 degrees. Construct an angle v measure the 125 degrees.
30 QUIZ 1. Name THE ANGLES using 3 POINTS. 2. WHAT room THE sides OF PAR?3. WHAT IS THE peak OF DAR? D p A R
31 WHAT room THE varieties OF POLYGON?HOMEWORK WHAT IS A POLYGON? WHAT are THE species OF POLYGON?
