Parts of an Angle ANGLES --is the union of two non-collinear

rays that will intersect at their

endpoints. Definition of Angles --is formed by two non-collinear

rays with a common endpoint. The

two rays are the sides of the angle. Angle- the union of 2 line segments

or two rays that have a common

endpoint.

Vertex- the point where the two rays or

two lines meet.

Rays- part of a line that starts at 1 end-

point and continues in one direction.

Sides- the two rays are the sides of the

angle. Angle Measurement The measure of an angle is the smallest

amount of rotation about the vertex from

one ray to the other. The unit of measure is the DEGREE and the tool used to measure is the

PROTRACTOR. WHAT IS A PROTRACTOR? How to find the Angle Measurement? The protractor is a tool used to measure angles in degrees. It usually has a curved top and a flat bottom shape and has marks with labels of the degrees. EXAMPLES OF PROTRACTOR WHAT IS AN ANGLE? HOW TO MEASURE ANGLES? Step 1: Place the center mark of the protractor

on the vertex and line up the 0 (zero)

mark with one side of the angle. The measure of this angle

is 40 degrees Step 2: Read the measure on the scale

which has the 0 mark you are using. Follow these basic steps EXAMPLE: The measure of angle <PQR is

50 degrees or 130 degrees. Both

are correct because you measure them from left and right respectively, it depends where you like to measure. WHAT ARE THE KINDS OF ANGLES? There are three kinds of angles: - Acute Angle - Right Angle - Obtuse Angle ACUTE ANGLES -- Angles that measure greater than 0 degrees and less than

90 degrees. RIGHT ANGLES --Note the special symbol like a box in the angle. If you see this, it is a right angle. The 90° is rarely written in. If you see the box in the corner, you are being told it is a right angle. OBTUSE ANGLES --The obtuse angle is the smaller angle.

It is more than 90° and less than 180°. Presentation By:
