与美国小学生一起学英文 Angles Let's think about a triangle.A triangle has three points, at each point, two lines meet together, this point is called an angle.How do people measure an angle?Angles are measured in degrees.Do you know what a surprising fact is? Do you want to know a ...
Every triangle has three sides and three angles on the inside. These angles add up to 180° for every triangle, independent of the type of triangle. In a right triangle, one of the angles is exactly 90°. Such an angle is called a right angle. To calculate the other angles, we need ...

You call it a circle . What can you see around you that looks like a circle? Another shape is square . A square has four sides . Each side is the same length( 长度 ) . A square has four corners called right angles( 直角 ) . A triangle is also a shape . The prefix “ tri ”...
Add 90 to the angle you just calculated, and subtract the sum from 180. This will give you the third angle. For example, 67.38 + 90 = 154.38 degrees. The third angle is 25.62 degrees. The Law of Sines Step 1 If you have a triangle with no right angles, use the Law of Sines. Ac...
