WALT: identify the missing angle 

The Triangle △ ▽ ◣

WALT: Group basic 2D shapes based on their properties  

TASK DESCRIPTION: For today's maths work we had to describe the types of triangles based on their properties. We also had to name the angles, obtuse, acute, reflex, right angle (90 degrees), and180 degrees angle. Obtuse is an angle that is more than 90 but less than 180, an acute angle is less than 90 degrees. A reflex angle is more than 180 but less than 360. 90 degrees is a quarter of 360 and is known as the right angle.
