Proportional side lengths refer to the relationship between the sides of two similar shapes. If two shapes have proportional side lengths, it means that corresponding sides of the shapes are in the same ratio. For example, if one shape has sides of lengths 2, 4, and 6, and a similar shape has sides of lengths 4, 8, and 12, the sides are in proportion since the ratios 2:4, 4:8, and 6:12 are all equal.
An equilateral shape for example is a regular polygon whose sides are all equal in lengths.
Angle Classifications:Obtuse (1 angle >90 degrees)Acute (all 3 angles
all side lengths are equal. has 3 sides
An infinite number. A polygon with any number of sides can be equilateral (ie have sides of equal length).
They must not all be equal.
All regular polygons are equiangular because their side lengths are equal.
Only a regular octagon will have 8 equal sides.
the shape is a regular shape if it has all the same angles and side lengths.
