Quizzical Quadrilaterals!

In our polygon unit we are learning about four-sided figures called

QUADRILATERALS!

Quadrilateral just means "four sides"
(quad means four, lateral means side).

Any four-sided shape is a Quadrilateral.

But the sides have to be straight, and it has to be 2-dimensional.

Many people were confused about why some shapes have more than one name. Here are some interactive quadrilaterals to help you explore and learn more!

Amazing Angles!

In geometry, we are learning about angles!


An angle is a  figure formed when two rays share the same endpoint.

 
Below is a special angle called a right angle. 
It is also called a 90˚ angle.

 

Any angle less than a right is called an acute angle. 

Any angle greater than a right is called an obtuse angle. 

Below is a quiz. Can you guess each kind of angle?

Do you see any acute, right, or obtuse angles in your house?

Tell us about them!

All Polygons Have Angles: Acute, Right, or Obtuse!

In geometry, we are learning about angles!

An angle is a  figure formed when two rays share the same endpoint.

 

 We have learned about the three types of angles.

Below is a special angle called a right angle. 
It is also called a 90˚ angle.

 

Any angle less than a right angle is called an acute angle. 

Any angle greater than a right is called an obtuse angle. 

We have also learned that polygons are closed plane figures with straight sides and that all polygons have angles! 

Below is a quiz using our own artwork!

Can you guess the angle in each of our pictures?
