Hi, everyone

We have a fresh start for the Geometry.

We watch the video first , practice some questions and problem-solving strategies.

Today we go through angle relationship and children are doing good.

Some children  have homework, please finish it, I will check it tomorrow.

Meeting time: tomorrow

(Problems:46-50)

Geometry1-Angle relationship

Corresponding angles are equal

Opposite/Vertical angles    are equal

Alternate interior angles    are equal

Alternate exterior angles    are equal

Interior angles on the same side of transversal  are supplementary angles 

Two angles are called complementary angles if the sum of their degree measurements equals 90 degrees.

Two angles are called supplementary angles if the sum of their degree measurements equals 180 degrees. 

Problem Solving: Angle relationship

1, Workout-2010-10 (70)

The supplement of an angle is 5.5 times the complement of the angle.  What is the measure of the angle?

2, school–coubdown-15-2010(60)

What is the degree measure of an angle whose measure is double the measure of its complement?
