Good morning everyone.
Well done for your work on symmetry over the last two days.
Today we are moving on to angles and lines.
Do you know any technical names for angles or lines already? ….
Parallel line– these lines run next to each other like train tracks and will never meet.
Perpendicular lines– these lines will eventually meet at a point.
Right angles– a right angle measures at 90 degrees. It looks like an L shape and is found in squares and rectangles.
Obtuse angles– angles that are bigger than 90 degrees but smaller than 180 degrees (a straight line)
acute angles– angles that are smaller than 90 degrees (I always remember that it is a cute, little baby angle!)
reflex angles– normally measured on the outside of a shape, these angles are bigger than 180 degrees
All of these are on a sheet linked below for you to refer to.
I would like you to classify the lines and angles highlighted on the shapes using the information above.
I have loaded the sheet in two formats as I know some of you were struggling to access.
Comment your answers.
