Maths Quiz - Level 3-4 Shapes - Angles (Questions)

Let's dive into the world of shapes - a big deal in KS3 Maths! One exciting feature? Angles! This quiz is all about testing if you've got the inside scoop on your angles.

Angles are like the cool way shapes turn or rotate, measured in degrees shown by this sign: ^o. A full rotation has 360^o, while a half-turn or straight line has 180^o. Shapes have set amounts of degrees too:

Picture squares - their corners have 90^o angles. Triangles? Their angles add up to 180^o. Less than 90^o is acute, between 90^o and 180^o is obtuse, and over 180^o is reflex. There's loads more to know, and this quiz is your guide!

Ready for some angle action? Take your time, read each question carefully, and ace this quiz. Don't forget the helpful comments after each question - they're like mini guides to boost your angle knowledge. Good luck!
