In this video, you will learn the difference between a convex quadrilateral and a concave quadrilateral.
A quadrilateral is a four-sided polygon, but what is a convex Quadrilateral?
Quadrilaterals come in different shapes and sizes, and many common shapes we encounter daily are quadrilaterals.
A few examples include,
square
rectangle
parallelogram
rhombus
kite
Quadrilaterals can be further divided by the interior angle measurements.
A convex quadrilateral has interior angles 180 degrees or less.
Quadrilaterals
Quadrilaterals can be further divided by the interior angle measurements.
A convex quadrilateral has interior angles 180 degrees or less.
A concave quadrilateral has an interior angle measure greater than 180 degrees. Most common quadrilaterals are convex, and they do not have any interior angle measure greater than 180 degrees.
CONVEX QUADRILATERALS
What is a concave quadrilateral?
A concave quadrilateral has a reflex interior angle measure. In other words, one interior angle measure is greater than 180 degrees.
CONCAVE QUADRILATERALS
A dart is one example of a concave quadrilateral.
A helpful method for memorizing the difference between these two types of quadrilaterals is to think of a cave for a concave quadrilateral. The reflex angle creates a cavity of a cave, which has an angle measure greater than 180 degrees.
