a Pentagon is five sided and CAN have 3 right angles.
a decagon
A seven sided shape is a heptagon.
An irregular heptagon.
The sum of the interior angles of a polygon is 2n - 4 right angles, where n is the number of sides. For a 24 sided shape this gives (2 x 24) - 4 = 44 right angles = 3960°.
a Pentagon is five sided and CAN have 3 right angles.
a decagon
A heptagon.
It is impossible to have a six sided shape with right angles since the lines would never meet, therefore it would not create a shape. The most right angles you can have in a shape is four. A six sided shape is called a hexagon. There are Regular Hexagons, meaning all the sides and all the angles are equal. Any other Hexagon with unequal sides and angles and called Irregular Hexagons. Each side must be straight, and the sum of the angles equaling 720°.
A regular 5 sided pentagon is one such example of a shape having no right angles
A seven sided shape is a heptagon.
You can make a four sided shape with 3 right angles, but it must have another right angle, too. So technically, yes.
a shape with 5 sides and 2 right angles is or are a pentagon so the answer is a pentagon
rectangle, square
In Geometry a 15 sided shape is called a pendedecagon polygon with 15 angles and sides
In Geometry a 15 sided shape is called a pendedecagon polygon with 15 angles and sides
Any shape with 4 right angels is a quadrilateral.
