Description
"Understanding acute angles and obtuse angles, solving problems" PPT courseware for preliminary understanding of angles
1. Review introduction and reveal new knowledge
Are there angles in math books? What angle is it?
I found that on every triangle, except for one right angle, the remaining two angles were acute.
2. In-depth exploration and consolidation of new knowledge
Let me put up a corner, and you can tell me what kind of corner it is.
This angle is larger than a right angle, it is an obtuse angle.
3. Solve problems
Can you use a set square to form an obtuse angle?
These two set squares have one right angle and two acute angles. Let's try to put them together.
Choose two sets of triangle rulers and spell out acute, right and obtuse angles.
