"Parallel and Perpendicular" Parallelogram and Trapezoid PPT

Description

"Parallel and Perpendicular" Parallelogram and Trapezoid PPT

Part One: Lesson Objectives

1. Combined with life situations, through independent exploration activities, initially understand parallel lines and perpendicular lines.

2. Experience the process of abstracting parallel lines from real space and cultivate the concept of space.

3. In mathematics activities, students can feel the real existence of mathematical knowledge in life, enhance their interest in mathematics, develop the habit of independent thinking, and cultivate the awareness of applying mathematics to reality.

Parallel and perpendicular PPT, part 2: exploring new knowledge

What will happen if you draw two arbitrary straight lines on paper?

Two straight lines that do not intersect in the same plane are called parallel lines. It can also be said that these two straight lines are parallel to each other.

How to express parallel lines

In the above figure, a and b are parallel to each other, which is written as a∥b and read as a is parallel to b.

Find the parallel lines in the diagram below.

Can you give some examples of parallelism in your life?

If two straight lines intersect at right angles, they are said to be perpendicular to each other. One of the straight lines is called the perpendicular to the other straight line. The intersection of the two straight lines is called the vertical foot.

Parallel and Perpendicular PPT, Part 3: Class Summary

What did you gain from today’s study?

Two straight lines that do not intersect in the same plane are called parallel lines. If two straight lines intersect at right angles, they are said to be perpendicular to each other.
