Task Description: For maths, were are learning about how to measure angles with protractors! When you measure an angle, you have to put one ray at 0°. You also have to put the intersection of the rays inside the small circle on the protractor. In the image above the question is “Is this angle acute, right or obtuse?”. An Acute angle is a angle less than 90° while and Obtuse angle is a angle more than 90°. A Right angle is exactly 90°. The angle in the image is a 90 angle because 60 – 150 is 90. 👍
