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.

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.

*

24

*

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.
