Yes, those polygons which have angles of 90 degrees and equal side lengths are called squares; those with uneven side lengths are called rectangles.

What type of polygons have all right angles?
Rectangles and squares are the only ones.
How many angles are in 2 squares?
A square has 4 interior right angles; 2 squares therefore have 8 angles.
Quadrilaterals have no right angles?
Certain quadrilaterals have right angles. Right trapezoids are the most general example. Rectangles are specialized right trapezoids, and squares are specialized rectangles. There may be more but I can't recall them. Many rhombuses and parallelograms have no right angles. However, they might (and then you'd probably call them squares or rectangles but they are also technically rhombuses, parallelograms and trapezoids).
All quadrilaterals have 4 right angles?
No, only squares and rectangles have 4 right angles.
What are 2 polygons with all 4 right angles?
They are a square and a rectangle
What are some polygons with right angles that are parallelogram?
Squares and rectangles.
How many polygons different polygons can be made with four right angles?
two, squares and rectangles
What type of polygons have all right angles?
Rectangles and squares are the only ones.
When do i use a right angle?
when you measure polygons that use right angles, like squares or rectangles.
Do all polygons have right angles?
No.
How many angles are in 2 squares?
A square has 4 interior right angles; 2 squares therefore have 8 angles.
What polygons has 4 unequal sides and no right angles?
A rhomboid
How do you tell if a square has right angles without measuring?
all squares have right angles
Do all squares have 4 right angles?
Yes, by definition. All squares have 4 right angles and 4 sides of equal length.
Quadrilaterals have no right angles?
Certain quadrilaterals have right angles. Right trapezoids are the most general example. Rectangles are specialized right trapezoids, and squares are specialized rectangles. There may be more but I can't recall them. Many rhombuses and parallelograms have no right angles. However, they might (and then you'd probably call them squares or rectangles but they are also technically rhombuses, parallelograms and trapezoids).
What is a polygons with four right angles and four congruent angles?
A quadrilateral, specifically a square or rectangle
How can you tell whether two polygons are similar?
Polygons will be similar if they have the same number of sides AND all of their angles are the same. All of their angles are the same if all but one of their angles are the same because with the same number of sides the angles must add up to the same thing. All squares are similar (4 right angles and sides of equal lenght). All rectangles are similar (4 right angles). We know two triangle are similar if two or mare angles are the same, or if one angle is the same and the two adjacent sides are the same length. Variations of this last proof may apply to some other polygons.
