Use rectangular paper to fold 45 ° and 135 ° angles respectively and draw them down with a pen

Use rectangular paper to fold 45 ° and 135 ° angles respectively and draw them down with a pen

As shown in the picture

Use a square piece of paper to make the following angles. (draw your folding method) 45 degrees 90 degrees 135 degrees 30 degrees

All the three red lines are folded in half, ∠ 1 = 45 & # 186; & nbsp; & nbsp; & nbsp; & nbsp; ∠ 2 = 90 & # 186; & nbsp; & nbsp; & nbsp; ∠ 1 + 2 = 135 & # 186; (i.e. ∠ NOD)
Extend BF so that C falls on point e of Mn, ∠ 3 = 30 & # 186;

What's the angle of a round paper folded twice?

Acute angle

Fold a piece of round paper in half twice, and the angle is ()
A. Flat angle B. obtuse angle C. right angle D. circumference angle

The angle of one fold is: 360 ° 2 = 180 ° and the angle of two fold is: 180 ° 2 = 90 ° A: the angle of two fold is right angle
