Which common quadrilaterals have two lines of symmetry?
Rhombuses and Rectangles
Are some parallelograms rectangles?
In fact, some are rectangles, but not all are.
Why are some rectangles squares?
All squares are rectangles also, but not all rectangles are squares, only equilateral rectangles are considered square.
Are some rectangles quadrilaterals?
All rectangles are quadrilaterals. A quadrilateral has 4 sides; all rectangles have 4 sides; thus all rectangles are quadrilaterals.
Are all rectangles parallelagrams?
Yes, all rectangles are parallelograms. However, not all parallelograms are rectangles.
Which common quadrilaterals have two lines of symmetry?
Rhombuses and Rectangles
Do triangles and rectangles have anything in common?
they both have straight edges
What DON'T rectangles and trapezoids have in common?
Trapezoids have only two sides parallel; rectangles have all four opposing sides parallel. Also, rectangles have 4 right angles, which is more than a trapezoid can have.
What is something that all rectangles have in common?
They all have four sides(quadrilaterils).
What does a rhombus and a rectangles always have in common?
all angles are right angles
What do rectangles squares and a right angle have in common?
All have 90 degree angles.
What do rhombuses and rectangles have in common?
Four sides, two pairs of parallel sides
what is the lateral faces of a rectangular prism?
They are all rectangles (or 2 squares and 4 rectangles).They are all rectangles (or 2 squares and 4 rectangles).They are all rectangles (or 2 squares and 4 rectangles).They are all rectangles (or 2 squares and 4 rectangles).
How many squares and rectangles are there in a 4 by 4 grid?
16 1x1 rectangles + 12 2x1 rectangles + 8 3x1 rectangles + 4 4x1 rectangles + 12 1x2 rectangles + 9 2x2 rectangles + 6 3x2 rectangles + 3 4x2 rectangles + 8 1x3 rectangles + 6 2x3 rectangles + 4 3x3 rectangles + 2 4x3 rectangles + 4 1x4 rectangles + 3 2x4 rectangles + 2 3x4 rectangles + 1 4x4 rectangle. A Grand Total of: 100 squares and rectangles. OR: A rectangle is formed by 2 horizontal lines and 2 vertical lines. There are 5 horizontal and 5 vertical lines so the number of rectangles is 5C2 * 5C2 = 10 * 10 = 100
A six sided block where all sides are rectangles?
Any rectangular prism. Most common is the cube.
Are some parallelograms rectangles?
In fact, some are rectangles, but not all are.
Why are some rectangles squares?
All squares are rectangles also, but not all rectangles are squares, only equilateral rectangles are considered square.
