Can a shape have equal sides but not equal angles?
A polygon with equal sides and and angles is a regular polygon. If its sides or angles are not equal it is irregular.
What do you call a polygon whose sides are not equal and angles are not equal as well?
There are two main types of polygon – regular and irregular. A regular polygon has equal length sides with equal angles between each side. Any other polygon is an irregular polygon, which by definition has unequal length sides and unequal angles between sides.
Which shape does not have equal angles?
irregular shape
An irregular shape doesn’t have equal sides or equal angles.
What shape has 8 sides and angles?
octagon
In geometry, an octagon (from the Greek ὀκτάγωνον oktágōnon, “eight angles”) is an eight-sided polygon or 8-gon….Octagon.

Can an octagon have all equal angle measures but not all equal side lengths?
No, this is not true.
Does an octagon have equal sides?
In a regular octagon, all the sides are equal in length, and all the angles are equal in measure. The interior angles add up to 1080° and the exterior angles add up to 360°. The interior angle at each vertex of a regular octagon is 135°.
What shape that has 8 sides?
An octagon is a shape with 8 sides and 8 angles.
What kind of shape has 5 sides and 5 corners?
Any shape with five corners or five sides is called a pentagon. Pentagons are 2D shapes that have 5 corners and 5 sides such as any of the shapes in the image above. The shape in the middle of the image is a regular pentagon because it has 5 sides that are all the same length.
A corner is where two sides meet. The perimeter property is the total distance around the edge of a 2D shape. The number of sides or corners tell us the name of which 2D shape we have . Any 2D shape with three corners or three sides is called a triangle .
How many sides and corners are in a triangle?
1 Triangles have 3 sides and corners. Any 2D shape with three corners or three sides is called a triangle . 2 Quadrilaterals have 4 sides and corners. The 2D shapes below all have four corners and four sides . 3 Pentagons have 5 sides and corners. 4 Hexagons have 6 sides and corners. 5 Circles have no corners.
What’s the difference between a corner and a side?
A side is a straight line in between two corners of a shape. A corner is where two sides meet. A shape is made when the sides form an enclosure. The length of all the sides added together is called the perimeter.
