"Understanding Right Angle" Understanding Graphics PPT Download

Part One: Exciting Introduction

Students, we already know that horns come in different sizes, but do they all have their own names? Today we will study this issue together.

Understanding right angles PPT, part 2: knowledge explanation

Find the corners in the objects below, draw them, and compare them.

An angle like the one below is called a right angle.

If we want to determine whether an angle is a right angle, we can use a triangle to compare it.

Tell me, which of the following angles are right angles?

You can use the triangle plate to compare.

Understanding right angles PPT, part three: practice and consolidation

Fill it out.

(1) A triangular plate has ( ) angles, including ( ) ( ) angles and ( ) ( ) angles.

(2) Arrange right angles, acute angles, and obtuse angles from small to large. ( )＜ ( )＜ ( )

(3) At 9 o'clock, the hour hand and the minute hand on the clock face form an angle ( ), and at 4:30, the hour hand and the minute hand form an angle ( ).

Is the following statement correct?

(1) Obtuse angles must be larger than acute angles. ( )

(2) The larger the opening of the horn, the larger the horn. ( )

(3) If you look at an angle under a magnifying glass, the angle will become larger. ( )

Understanding right angles PPT, part 4: knowledge summary

Angle can be divided into three categories: right angle, acute angle, and obtuse angle.

An angle smaller than a right angle is an acute angle, and an angle larger than a right angle is an obtuse angle.
