Angles, Angles, Angles!

RIGHT ANGLES-

Right Angel is one corner of a square that is purely 90 degrees.(Genna)

To a right angle there is a vertex, two lines two arrows and they are doing the vertex with their feet, and the arrows with their arms.   (Ella)


OBTUSE ANGLES-

Obtuse angles have to be over 90 degrees and can’t be less than 90 degrees. (Genna)

An obtuse angle is bigger than a right angle. It is 2 rays that intersect with a vertex. Jacob, MJ, Courtney, Brett, Phing, Jacob and Shane did an obtuse angle with their arms. On a clock, examples of an obtuse angle are 12:30, 3:45, and 8:15. (Phing) 

An obtuse angle is bigger than 90 degrees. On the picture, it is like a straight line. (MJ)

ACUTE ANGLES-

 

An acute angle is smaller than a right angle. There are lots of acute angles on a clock. (Phing)

Amelia, Ella, Genna, Elijah, Makenna, and  Bethany are forming acute angle. Amelia and Bethany make the vertex and Makenna and Elijah are the lines. Ella and Genna are the arrows. Acute angles have to be less than 90 degrees. (Amelia)
