In this activity, we will be spotting different types of angles. There are 3 types of angles that we will be looking for and we are going to share the tips for doing so!
Have you heard of these terms before?
ACUTE - This is an angle that is less than 90°. (This is the symbol for the word degree)
(Sneaky tip - If someone is called 'cute' this could be because they are little!)
OBTUSE - This is an angle that is more than 90° (a right angle) but less than 180° (a straight line).
RIGHT ANGLE - This is an angle that is exactly 90 °.
(There are many everyday objects that have a 90° angle, think about the corner of your ruler this is 90° and can be used as a quick angle checker, by holding it to where the 2 lines meet)
Example
Sort the angles into acute and obtuse.
(b) 
(c) 
(d)
(e) (f)
Answer
Acute angles: c, d, e.
These are less than 90° (a right angle)
Obtuse angles: a, b, f.
These are more than 90° (a right angle) but less than 180° (a straight line)
