Shapes. They form an important part of KS3 Maths. There are many aspects to shapes, like sides, corners and area. This quiz looks at angles.
There are certain 'rules' about angles. For example, the angles in a triangle always add up to 180o. There are also different names for different types of angles - acute, right-angled, obtuse and reflex.
Can you tell an acute angle from an obtuse angle? Do you know how many degrees there are in a circle or in a square? Are you familiar with the angles of a regular pentagon or a regular hexagon? Well, this quiz will find out!
The ten questions that follow will test your knowledge of angles. Take your time and read each question carefully before choosing your answers. And don't forget to read the helpful comments after each question. They might help you gain an acute knowledge of angles.

Acute angles are less than 90o
|
Right angles are exactly 90o
|

Obtuse angles are between 90o and 180o
|
Reflex angles are between 180o and 360o

The angles on a straight line add up to 180o
|
The angles in a circle add up to 360o
|

90o + 195o + 75o = 360o
|
The angles in a triangle add up to 180o

All angles in a regular pentagon are the same. (The length of the sides are also the same)
|
Remember that all the angles in a regular hexagon are the same and all the lengths of the sides are the same
