They involve only the base and vertical height.The formula for a triangle is half that for the corresponding parallelogram.
All rectangles are parallelograms but a rhombus for example, is a parallelogram but not a rectangle.
Triangles are alike or similar to each other when their sides are proportionate and have the same angles.
They are both 4 sided quadrilaterals but a trapezoid has only 1 pair of parallel sides whereas a parallelogram has 2 pairs of parallel sides.
The only way they are both alike as if they a equilateral.
They are both polygons
All rectangles are parallelograms but a rhombus for example, is a parallelogram but not a rectangle.
They are alike in that they are all triangles when you close them. They are different because they are all different degree amounts.
Triangles are alike or similar to each other when their sides are proportionate and have the same angles.
There are all three sided polygons. The sides can be equal in length or unequal.
They are both 4 sided quadrilaterals but a trapezoid has only 1 pair of parallel sides whereas a parallelogram has 2 pairs of parallel sides.
The only way they are both alike as if they a equilateral.
Both have two sets of parallel lines, but a rectangle forms four equal 90 degree angles. A parallelogram does not have four equal angles.Read more: How_are_a_rectangle_and_a_parallelogram_diffrent
They are both polygons
a square are alike to a parallelogram because they have parallel sides
They both have two sets of parallel lines. A rectangle is a parallelogram, but a parallelogram is not a rectangle.
A trapezium and a parallelogram are both quadrilaterals with at least one pair of parallel sides.
They are alike inasmuch that a rectangle can be split into two right angle triangles
