What determines whether two shapes are similar?
the same number of sides and internal angles but not the length of the sides.
What is the name for shapes with sides the same lengths and same sized angles?
regular polygons
Do all two dimensional shapes have the same number of sides and angles?
No. A triangle has 3 of each, whereas a square has 4 of each.
What are similarities of congruent shapes and similar shapes?
The angles for congruent shapes and the angles in similar shapes are all the same. All the sides are also proportional in both. Basically, all congruent shapes are similar but not all similar shapes are congruent.
Why does a polygon have more sides than angles?
It doesn't ! It has the same number of sides as angles !
What determines whether two shapes are similar?
the same number of sides and internal angles but not the length of the sides.
Are regular shapes shapes with all the same angles and sides?
Yeah.
How are regular and irregular shapes the same?
Regular shapes:all sides and angles are the same Irregular shapes: different angle and sides
Examples of regular shapes?
Regular shapes are shapes where all the sides and angles are equal. One example of a regular shape is a square because all the sides are the same and all the angles are 90 degrees.

regular polygons

What polygons are irregular and regular?
Regular polygons are when all the sides are same length and all the angles are the same size. Irregular polygons are shapes where the sides are not all the same and the angles are different.
What do quadrilaterals have that other shapes don't?
Four sides, four angles, the same sum for external and internal angles.
Do unusual shapes and normal shapes have the same name if they have the same number of sides?
Yes. For a given number of sides, you can have "regular" polygons where all sides are of the same length, and "irregular" polygons with different lengths and angles. A "concave" polygon is one having interior angles greater than 180°, so that line segments fall between two other points on the shape, such as a tetragon formed as a nested letter V.
How many angles does a hexagon have?
A 6 sided hexagon has 6 angles that add up to 720 degrees
Which figures have the same number of sides vertices and angles?
Vertices and angles are the same thing. Any polygon has an equal number of sides and vertices (and, therefore, angles).Vertices and angles are the same thing. Any polygon has an equal number of sides and vertices (and, therefore, angles).Vertices and angles are the same thing. Any polygon has an equal number of sides and vertices (and, therefore, angles).Vertices and angles are the same thing. Any polygon has an equal number of sides and vertices (and, therefore, angles).
How do you decide a figure is congruent?
If all the sides and all the angles are the same and in the same order, the shapes are congruent.
