## Presentation ~ above theme: "ANGLE A number FORMED BY two NONCOLLINEAR RAYS v A typical ENDPOINT."— Presentation transcript:

1 2 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. 7 AN edge SEPARATES A airplane INTO 3 PARTSINTERIOR ANGLE- point D EXTERIOR edge – allude H THE edge ITSELF P, A, W,C ●H ●D 8 instances 9 specify name AN angle 10 USING 3 POINTS.

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 5WXY, 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.
