Warm-Up

Warm-Up Find the next two numbers in the

sequence: 3, 7, 15, 31, __, __ Draw four points M, A, T, H such that

and are opposite rays and and are the same ray.

Find the distance between the points (-3, 4) and (3, 6). Simplify your answer.

Use the Segment Addition Postulate to solve for x if = 4x – 3, = 3x – 10 and = 6x + 8. L H S

GEOMETRYAngles and Their Measures

Learning Outcomes I will be able to classify angles into

groups according to the measure of their angles.

I will be able to use the angle addition postulate to determine the measure of angles that are separated into two or more angles.

Vocabulary Angle: An angle consists of two different

rays that have the same initial point. Sides of an angle: The rays are called

the sides of the angle. Vertex of an angle: The initial point is

the vertex of the angle. Measure of an angle: The absolute value

of the difference between the two sides.

More Vocabulary Interior of an angle: The interior of an

angle is any point between the points that lie on each side of the angle.

Exterior of an angle: The exterior of an angle is all the points not on the angle or in its interior.

Adjacent angles: Two angles that have a common vertex and side but no common interior points.

Classifying Angles What geometric figure does a straight

angle make?

How Many Angles Are There? NAG or GAN GAL or LAG LAE or EAL NAL or LAN GAE or EAG NAE or EAN

Angle Addition Postulate

Basically, we can add two or more angles together to get a bigger angle, or we can break two angles apart to get a smaller angle.

Angle Addition Postulate Find the measure of the unknown angle.
