3 angle A figure FORMED BY 2 NONCOLLINEAR RAYS v A usual ENDPOINT.

4 angle The two NONCOLLINEAR rays (ray BP & beam BC) room the sides of one angle.

5 angle The allude where the rays intersect is dubbed the vertex of an angle.

6 angle MNEMONIC S- Sides are 2 non-collinear rays. E- Endpoint is additionally called vertex. R- Rays are the 2 sides. V- vertex is the typical endpoint.

8 instances

9 specify name AN angle

10 **USING 3 POINTS. EXAMPLE: ABC orCBA PBW or WBP**An edge is named by: using 3 POINTS. EXAMPLE: ABC orCBA PBW or WBP

11 An angle is named by: 2. By THE peak ALONE. EXAMPLE: B

12 An angle is named by: 3. BY using A NUMERAL. EXAMPLE: 1 1 1

13 practice 3 2 1

14 **NAME THE ANGLES using 3 POINTS**NAME THE ANGLES utilizing A numeral 3 2 1

15 **WHAT space THE political parties OF angle 3.You are watching: Two noncollinear rays with a common endpoint**ANOTHER name OF angle 1. B or ABW PBC or ABC Segment AC and also ray AP 3 2 1

16 **WHAT IS THE common SIDE of 2 and also 3?**Segment AC 3 2 1

17 **Name angle Name the 3 angles in the diagram. Example 5**WXY, or YXW YXZ, or ZXY WXZ, or ZXW You must not name any of these angles X because all three angles have actually X together their vertex.

18 Degrees: Measuring angle Angles space measured in units called DEGREES and also classified according to your measures.

19 **Acute angle an angle measuring between 0 and 90 degrees**

20 **Obtuse angles an angle measuring in between 90 and also 180 degrees**

21 **Right angle an edge measuring specifically 90 degrees.**

22 **Obtuse angle an edge measuring in between 90 and 180 degrees**

23 **Degrees: Measuring angle We measure the size of one angle using a machine called the PROTRACTOR.**

24

25 exactly how TO use A PROTRACTOR

26 **Place the center suggest of the protractor top top the crest of the angle.**

27 **Line increase the note labeled 0 top top either range with one side of the angle.See more: What Kind Of Guitar Does Bruce Springsteen Play, Get To Know Bruce Springsteen'S One**

28 **Read the range where it falls on the other side of the angle.**

29 **Use a protractor because that exercises 1-2**Construct an angle v a measure of 45 degrees. Build an angle with measure of 125 degrees.

30 **QUIZ 1. Name THE ANGLES making use of 3 POINTS. 2. WHAT room THE sides OF PAR?**3. WHAT IS THE vertex OF DAR? D ns A R

31 **WHAT space THE species OF POLYGON?**HOMEWORK WHAT IS A POLYGON? WHAT room THE varieties OF POLYGON?
