ANGLES!By: Melissa Pinnell
ABOUT ME! I am 19. A sophomore, studying Early Childhood
Ed. I have not completed any observation
hours or tutoring. I do however teach children’s church, for
the experience. I have not yet created a philosophy.
STANDARDS! M2G1. Students will describe and
classify plane figures (triangles, square, rectangle, trapezoid, quadrilateral, pentagon, hexagon, and irregular polygonal shapes) according to the number of sides and vertices and the sizes of angles (right angle, obtuse, acute).
STRAIGHT ANGLE! Can anyone tell me what a straight
angle is? A straight angle is an angle that is 180°
exactly!
OBTUSE ANGLE! How about an obtuse angle? An obtuse angle is an angle that is
greater than 90° but less than 180°!
RIGHT ANGLE! Now, can anyone tell me what a right angle
is? A right angle is an angle that is 90° exactly!
If it is a right angle then it will always have this little box!
ACUTE ANGLE! Can anyone tell me what an acute angle
is? An acute angle is an angle that is less
than 90°!
